Adobe Sign plugin in Microsoft Word
Hello,
I'm trying Adobe Sign for a few days and I've dowloaded Adobe Sign plugin in Microsoft Word Store (by using "Insert > Office Add-ins" in Microsoft Word). A lateral panel appears if I repeat the process (Insert > Office Add-ins > Adobe Sign), and I can use Adobe Sign to ask for signatures.
Adobe Help says new icons are added in the ribbon at the "Home tab", but unfortunately it's not. Indeed, as you can see in the picture below, Adobe Sign icons are missing.

I tried to reboot several times Microsoft Word, to re-add Adobe Sign Add-in from Microsoft Word Store, to customize the ribbon, but nothing to do : Adobe Sign Add-In is nowhere.
Can you help me for displaying this Add-in in Microsoft Word ?
Thank you for your help.
