No other steps, except re-starting Gimp. Works as shown in the video.

Edit: Checked again in Windows and can not find problem.
You did unzip it ?  When editing careful not to introduce any spaces scale=0.5 is correct  scale  = 0.5 is not

New day, modified plugin with 1.2 as the GEGL Saturation value. There is no 1200, the scale goes from 0.0  to 10.0

Included in the zip is a simple text editor if (when) you need to modify the scale value. It is not difficult.

This a video demo, from unpacking the zip through to applying BIMP.  https://youtu.be/JNlbuYJlHEQ

I do not think so, there is a way with the g'mic plugin of comparing a before / after pair, extracting a color-look-up-table (CLUT) and applying that to other images. Not sure you can apply that particular gmic filter with BIMP.
Another way is, adjust an image with the color-curve tool and save the curve settings as a file. BIMP will apply that color-curve using the file.

@PixLab
nice screenshots, pays to read the first post as the OP specifically does not want to use hue-saturation.

Tried again today with  a more "serious" gradient-chart and white writing on black BG
A neutral for you, if you want to try


Color>Saturation quickly bleed out on the white writing especially in the cyan and green (scale up to 2), but all colors will bleed on the white when pushed hardly (scale ➤ 2)

Color> Hue Saturation seems to be a proper one as at equivalent saturation (full throttle in the Hue-Saturation window) cyan and green are not bleeding out

When I said a proper one ->  it seems to be... but rich2005 got the point when he says "I guess it is all in the eye of the beholder"

Is this using BIMP the batch plugin ?  If it is you can not use theColor -> Saturation filter directly. It is GEGL and not selectable as a "Other Gimp Operation" in BIMP.

You can 'wrap' the GEGL command in a python script which BIMP recognizes. If you are willing to do a little editing, a basic python plugin is attached.
First find the Saturation value you need from using Gimp on a typical image. That is the Scale value.  Get a decent text editor (not notepad or wordpad)  Usually Notepad++ and replace the value scale=10 in the script at line 52 eg. scale=0 is total desaturation.  scale=2.5 is well across the GUI slider.
[code]
- - - - - -
def for_gegl_command(image, drawable):
# put your GEGL command here
# saturation scale minimum value 0  max value 10
    gegl_graph_string="saturation scale=10 colorspace=0"
- - - - - -
[code]

Unzip the attachment. For windows the plugin goes in C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\plug-ins  
The plugin registers in the Tools menu and you can try it out on an image.

In BIMP it is a "Other Gimp Procedure"

I normally use linux but tried out in a Win10 / Gimp 2.10.24 and it works with a few flashing on / off terminals as BIMP calls the plugin.

Not making separate screenshots for this one see:   https://i.imgur.com/Gta0EUX.jpg  Top the images used. Middle - the BIMP function Bottom - BIMP working, between first and second image. Not going to break any speed records but does get there.
EDIT: Thats it for today, bye

I really appreciate the information you sent.  I went as far as installing Notepad ++ and viewed the attached file hoping I might be able to figure it out.  I am totally a beginner when it comes to scripting so even with your guidance I couldn't figure out what the syntax should look like in the .py file.  

I don't suppose you would go so far as to give me a section of code that I could insert that would give me Color > Saturation = 1200?

Or if there is an easier way, like doing a batch command that would utilize the saturation level of an existing file?

Hi Rich2005, are you aware of a batch color saturation plugin for GIMP 3.10?  When I upgraded I lost the batch menu item.  Thanks.
