Android Meeting Zoom SDK - PKCE Oauth Flow Not working

Hi,

I am facing the issue of integrating the Zoom Android Meeting SDK in our app, Previously it was working fine when we logged it through
UserName & Password, after upgrading I am stuck in oAuth Flow, I am trying to implement it through PKCE.

Step I followed-

1.Upgraded the Android Meeting SDK with version v5.12.1.8952.

2.Zoom SDK is getting initialized successfully.
3.Now I am trying to use the PKCE oAuth flow, but once i am executing this code flow, nothing get happens -
Uri uri = Uri.parse("https://zoom.us/oauth/authorize")
   .buildUpon()
   .appendQueryParameter("code_challenge", createCodeChallenge())
   .appendQueryParameter("code_challenge_method", "S256")
   .build();
   
   Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

Can you please suggest which step I need to follow.
