Had to take your icon from the image you posted, so a bit on the small side.

1. Make sure the image is in RGB mode Image -> Mode RGB

2. Make sure the image has transparency: Layer -> Transparency -> Add Alpha Channel (if greyed out it already has an alpha-channel)

3. Use the fuzzy select tool,  click in the white background to create a selection.

4. Grow the selection by one or two pixels Select -> Grow

should look like this: https://i.imgur.com/PcDad4P.jpg

5. Use the Color-to-Alpha filter Colours -> Colour to Alpha using default white.

looks like this: https://i.imgur.com/m5gz3W0.jpg

6. Ok that, kill the selection Select -> None,

Export as a png file which will keep the transparency.
