A couple of nits:

8.2.  OAuth Implicit Grant Authorization Flow

   The OAuth 2.0 implicit grant authorization flow as defined in
   Section 4.2 of OAuth 2.0 [RFC6749] generally works with the practice
   of performing the authorization request in the browser, and
receiving
   the authorization response via URI-based inter-app communication.
   However, as the Implicit Flow cannot be protected by PKCE (which is
a
   required in Section 8.1), the use of the Implicit Flow with native
   apps is NOT RECOMMENDED.

NOT RECOMMENDED is not actually a construct allowed by RFC 2119, I think
you should reword it using "SHOULD NOT".

It would be good to add RFC reference for HTTPS URIs.
