Is the option to add a signature to a calendar invite gone?

I just updated to the newest Outlook version, and now when I create a calendar or meeting invite, there is not "insert" tab where I can select to add my signature. Am I missing something? I have spent all day trying to figure this out. I do not want to manual type or copy and paste my email signature for every event invite, but it's important to get my contact info out there. Is this feature.
