[CLNP-8774] fix: prevent TypingIndicator from leaking group channel handlers on unmount - #1448

How should I remove sensitive data from a pull request (PR)?

1. Delete and Regenerate the Key(recommended):

• Regenerate new keys.
• Invalidate the existing ones to prevent unauthorized access.

2. Force Overwrite the Commit:

• Remove the sensitive information and commit the modified file.
• Use git rebase -i HEAD~i or git revert <commit hash> to modify the commit history.
• Force push the changes (git push --force).
  Use git push --force cautiously to avoid data loss and collaboration issues; always notify your team.

3. Contact the Administrator:

• Report the commit and file containing sensitive information to the administrator.
• Follow the administrator's instructions.
• Receive additional instructions if necessary.
