Include permission

so i was trying to include the permission for my app during build, a app permission call 'READ_CONTACT" is not found in the list to include and even after selecting the include its not in red colour is displayed in grey.

Um, what do you mean by included permissions? Can you send a screenshot about the view you’re talking about?

Basically you should not be including any permissions not automatically included by flow functions. READ_CONTACT would be included by Get all contacts flow function, for instance.
