Changing the name of a universal channel once its created will only reflect on the chat app you're using.
For example, if you change the name of a universal channel on Microsoft Teams, that change will not be reflected in Slack or Webex. You would have to ask someone who has privileges on Slack or Webex to change the channel name on their side.
