Remove Jira Cloud chat message from teams group

I added the Jira Cloud app to our Teams group...

And now I cant remove the chat massage from Jira Cloud...

"Hi, I’m here to help you manage your Jira issues. To begin with, please type 'connect' to connect to your Jira."

I have uninstalled the Jira app from Teams.. But the message from the Jira bot is still there.. And I cannot find any way to remove this message..

I guess one solution would be to delete the group.. And set it up again.. But that would not be the best solution for me...

Thanks for help!!
