I basically need guidance to implement the below described,

PKCE OAuth and the Meeting SDK for Android (zoom.us)

In the above page in the section PKCE OAuth and the Meeting SDK for Android (zoom.us)

I am not sure what is  'OAUTH_URL', and 'URL_SCHEME', Can anyone please help me to understand what values to put for these.
