It is actually a more efficient method
Check in the gradient drop down that you do not have FG to BG hard edge set in case FG to Transparent did not 'fix'
You also need to check after making any adjustment to the gradient. It then becomes 'custom' - easy to miss.
Then it is start in the center and draw the gradient out-over. The gradient can go in either direction. Adjust the center point slider to get the desired effect.
Again assuming a circular ring rather than a circular disk, method is the same for both.
Just about make the 60 second limit
