I have created a form that will send the information to a sharepoint list. The user will choose multiple names on the form as a multiple choice type question. (this part works) I would like to them send a message to those multiple people through teams. (The part that doesn't work) If the form has a single choice person selection, I can get it to work this way:

However when I try to do the same with the multiple selection people group, It will not work. this is how I have it set up in the SharePoint.

Any suggestions would be helpful. Thank you
