There are a couple of ways, make a gradient, then crop out the center, however

First, do you know how to subtract from a selection? Make your initial
elliptical selection in Replace (first icon) mode. Fix that by clicking inside.
Put the tool into subtract mode (third icon) draw it in and fix (click in
selection)

That gets an annular selection that you can fill. Please work on a new
transparent layer, easy to correct, that is what they are for.

A black to white gradient will fill the selection. Tool options - gradient
reversed - Blend color space linear - Shape radial. Draw it in from center of
circle to edge of circle. In Gimp 2.10 there is a mid-point control for
adjustment, but not enough for a clean white-to-black in the ring. see shot01.

Click on the gradient line to create a stop (splits the gradient) In the
dialogue change Left/Right color to BG (which is white in this case). Adjust the
positions of the stop, endpoint (black) and the centerpoint between the two to
suit. see shot02

best of luck.

This is the worst Gimp forum ever, that recaptcha is plain stupid
