Tips

Using comments and tagging people

Unfortunately for guest users (non Fenêtre personnel) it is not possible to tag a person in the comments through an '@'. This is a limitation in Teams.
Until this is solved within Teams, you can put an '@' in post channel with a link to the item.

Creating screencaptures for reports

As a Fenêtre customer you can use the Fenêtre Capture tool for free, this free screen recording app is designed to create screenscapture quickly, and then add annotation for bug reports.
