Restricting access to user groups with Control Panel access only I know I can restrict template output to Admins only with : 

{% if currentUser.admin ?? false %}

…and to any logged in user with:

{% if currentUser ?? false %}

And I’m aware of accessCp as a permissions handle.

Can I use that, or similar, to restrict template output to any user group that is allowed to access the CP – without having to cycle through specific user groups in the template?

I tried: 

{% if currentUser.accessCp ?? false %}

…but that doesn't work.

I'm using Craft 3.1.29.
I’ve figured out what I was missing. I needed to use can: 

{% if currentUser.can('accessCp') ?? false %}

:)
