How to get community appWidgets rights?

Question

API

I need to get appWidgets permissions for the community
. I've read a bunch of docs, but I didn't understand anything.
The only thing I understood is that I need to create a VK application and execute bridge, but how to do it?
https://api.vk.com/method/execute.VKWebAppGetCommu... returns error
User authorization failed: no access_token passed

Answer 1

Because the token does not have enough rights
