Creating an Outlook web add-in with Visual Studio

I have just watched https://mva.microsoft.com/en-us/training-courses/advanced-office-addin-development-with-outlook-14045?l=Ky6tSjnmB_5200115881, where Microsoft's Richard diZerega is showing how to create a new  Outlook web add-in with Visual Studio.

His version of VS shows this, whne he selects Project/New:

but my VS 2107 Enterprise shows this

The difference being that he has various options for Task pane/Content/Mail and Email/Appointment Read/Compose.

The projects which I generate read email, whereas I want to add a task pane to the mail compose dialog.

I could edit the manifest, indeed that is currently my only option, but it would be so much easier if I could check a few boxes and generate a manifest.

(How) can I have the dialog which he has? It it dependant on the version of VS, or its it a VS add-in?
