The problem is the gif transparency is binary - either on or off.
What you need to do is first convert to indexed mode Image -> Mode -> Indexed and apply dithering. That breaks the semi transparency up into dots according to the degree of transparency.
Then since you have updated to Gimp 2.10, consider using the drop shadow tool rather than a gaussian blur. It really is a versatile tool and maybe more than one glow layer in incremental stages, up-to-you. Export as a gif using the replace layer option.
