Telegram Trigger not sending message to a GroupID (-XXXX)

I configured a new telegram trigger to test the integration. When I mention a CHATID, messages a re getting delivered with no issues. However, when I mention a GROUPID (-XXXXXX) then messages are not getting delivered. Checked all privacy settings/permissions but issue is not resolved.

Hey @RAJEEV_GUJRAL hope all is well. Welcome to the ocmmunity.

It doesn’t look like you have the right ID for the group. Can you share how you retrieved that ID?
