Custom app deeplink to the meeting sidepanel is broken

Hello @PraveenPatelTQ, 
Hope you are doing well!!

Deep link doesn't open in the meeting side panel in the following scenarios:

• There's no active meeting.
• The app doesn't have sidePanel context declared in the app manifest.
• openInMeeting is set to false in the deep link.
• The deep link is selected outside of the meeting window or component.
• The deep link doesn't match the current meeting, such as a deep link created in another meeting.
  
  Could you kindly check if there were any issues with your meeting URL and confirm?
  Test the deep link in both the Teams desktop client and the web client to check if the issue is specific to one platform.
