Issue Summary

While creating an MS Team channel with an automation rule, if you edit the prefix or suffix and then leave it empty, the channel will be generated as -

-.

Steps to Reproduce

1. Create an automation with the Create Microsoft Teams chat or meeting for incident action.

4. Execute the rule. Observe that the channel is created with a hyphen at the front and back of the channel name.
5. Exporting the rule to a JSON file, we can see that the conversationNamePrefix and conversationNameSuffix have an empty value, instead of null.

"conversationNamePrefix": "", 
"conversationNameSuffix": "",
"conversationDescription": null, 

Expected Results

The channel name is created with the issue key only.

Actual Results

The channel is created with a hyphen at the front and back.

Workaround

Delete and add the action again, without editing the prefix and suffix fields.
