Correct way to use Template 7 on recent versions?

Hello, I know that Template7 was removed from Framwork7 Core and replaced by template literals.
The migration guide states that T7 can be used and called manually, but I would like to see and example of the proper way of using it with a Router Component.

(My motivation is that i am mataining a project made with v5, and t7 each,if,js_if… seems much more readable)

Thanks!
