OAuth2 Docs Clarification: token redirect_uri MUST be the same as auth

[paulwongx]

I spent a good number of hours trying to figure out why my access_token request wasn't working.... and I'm sure there are plenty of others who are encountering this issue.

I only figured it out because of this person's answer on StackOverflow: https://stackoverflow.com/a/70280164/12894626

I know this can be said that I made a noob mistake, but PLEASE explicitly state that the auth redirect_uri needs to be the same as the token redirect_uri otherwise it won't work!

Otherwise, people are just wasting their time debugging with http://, https://, no http, no www, using different urls, debugging the code when there's no issue with the code, trying on postman instead of code, etc. etc.

tldr; Explicitly state here that auth redirect_uri must be same as token redirect_uri
