Getting access to a "Personal Access Token"

I am trying to setup the PowerApps/FIgma (Preview) integration. It tells me to go into Figma settings and get a “personal access token”.

When I go into the Figma settings the field to setup the personal access token is greyed out.

How do I create the “Personal Access Token”? And has anyone else setup and used the Preview integration with PowerApps?

I’m hitting the same issue. Windows 11, Firefox browser.
