This pull request addresses

This PR adds support for the alias parameter to the joinMeeting function and updates the corresponding unit tests to verify its correct handling.

by making the following changes

joinMeeting Function:
Added the text field in a samples page to enter the guest-user-name so the same name will be visible on the remote side as well and this text field name is an optional if user won't enter the name by default the system name will be taken

• Included the alias parameter in the joinMeeting function call to ensure it is correctly passed along with other parameters.
  These changes are used for the user in such a way that when the user is trying to join the meeting by providing a name according to their wish it's going to be displayed on the remote side. so for this, we are adding one param as alias and passing it into the joinMeeting options

added an text field to enter the guest user name please do watch screen recording

Just a nitpick comment and rest looks good.

However, can we add a text field in the Join meeting section of the sample app to get an alias name? If the box is empty, we need not send anything. This way, it'll be easily testable in future.
