Hi Vosidiy, short answer: you can’t.

Figma are not approving new creators anymore for paid files. But you still can sell plugins or widget.

You can view the detailed articles here:
selling community resources

Hi there!

Just confirming what ​@Jonathan-Liausvia  mentioned—we're currently not approving new creators to sell paid files on the Community at this time.

For more details, feel free to check out these Help Center articles:

• About selling Community resources (already shared)

• Publish files to the Figma Community

Hope this helps clarify things!
