Thanks. Before we can review this in detail, it will need tests. See our README, which says that and has links to more resources.

This also makes several changes that seem unrelated to the issue this is meant to solve — for example removing the loading indicator. If those are unintended, you'll need to remove them. If intended, please make clear in the commit messages why those changes are desirable. See the links in our README for Zulip's Git style guide.

I apologize for submitting the PR without proper tests and for including unintended changes
As this is my first contribution to Zulip, I'll:

1. Close this PR
2. Review the README thoroughly, especially the testing guidelines and Git style guide
3. Create a new PR that:
   • Focuses solely on the video zoom functionality
   • Includes comprehensive tests
   • Follows Zulip's Git commit message guidelines
     I appreciate the guidance and look forward to submitting a properly structured contribution.

No need to close a PR and open a separate one — it's better to update the same PR. That keeps the discussion thread together. (You can still reopen this one.)

Also, it looks like CI is failing; that will also need to be fixed. 🙂

Give me some time, I'll fixing the issue within the guidelines 😄

I keep getting NDK version error and trying fixing it using the upgrade script but it requires linux environment to run, can anyone guide me a little ?

See the section in the README about asking for help — you'll get answers more effectively in Zulip following those guidelines than by trying to have the conversation in this GitHub thread.
