Archive page for custom post type and taxonomy

Hi,

I have a website with multiple custom post types. They share a custom taxonomy called “Departments”.

Basically the website is split up into 3 departments, all sharing a photoalbums, calendar and some other custom post types.

The problem is, I can’t seem to make a proper “Nice permalink” like so:

https://example.com/<custom-post-type>/<taxonomy>/<taxonomy-value>/

The only thing that works is this:

https://example.com/<custom-post-type>/?<taxonomy>=<taxonomy-value>

It should display an archive page with -for example- all calendar items (custom-post-type) within a specific department (taxonomy).

Is there a non-hacky way to do this? All I can find is hacky workarounds, posted at least 3 years ago.

Thanks!
