php - Custom post type category selector in a page

one text

I have a site that has a custom post type: Testimonials. Inside it some Advanced Custom Fields:

What I??�m looking to set up is, when someone creates a new Page, there??�s a dropdown/select option in there, too. The dropdown will list each Category from the Testimonials custom post type. Then, on the front-end, the testimonials from that category will display. So if someone chooses ???fire??? as a category from the dropdown in a new Page they??�re making, when that page is viewed on the pubic front-end, it will be displaying only the testimonials from the ???fire??? category.

I??�m just unsure how to set this up. I saw that there??�s a Taxonomy option in ACF (https://www.advancedcustomfields.com/resources/taxonomy/). I??�m wondering how I would set up the ACF Field Group properly for what I want it to do, and then the second half would be the page template??�s actual PHP that would basically say ???Display testimonials only from the selected category.???

Can anyone help me achieve this goal? I would very much appreciate it! Thank you in advance ??��

EDIT:

I got a little bit closer to my answer, i removed the taxonomy from the ACF field group and added a custom taxonomy with CPT.

From here on I can query every post related to that category:

My only question is now is, if someone chooses ???fire??? as a category from the dropdown in a new Page they??�re making, when that page is viewed on the pubic front-end, it will be displaying only the testimonials from the ???fire??? category? Many thanks in advance!
