Feature-Policy is deprecated and replaced with Permissions Policy:
Browsers don’t support permission policy yet and there’s no documentation (that I understand with reasonable time spent) on how to use it.
The header has now been renamed to
Permissions-Policyin the spec, and this article will eventually be updated to reflect that change.
Once that changes, I will look into it. Waiting for major browser supporting and documenting that such as Mozilla MDN.
looks working good on main website and forums.
