Count of nodes filter in views for a taxonomy with depth sorry for my English.
In views, Drupal 8/9, is it possible to have the count of nodes for a taxonomy-term with depth?
I would like to have it for the filters in views.
I can't find any modules to get this information.
Maybe I don't know how to look or a complex module gives this possibility but I couldn't find it.
Aggregation doesn't really help me. Performance is not a problem.
There are several ways to do it, based on how you are going to manage your content.
But for your problem I guess the solution can be this:
1. In Fileds: add Taxonomy term: Name
2. In Relationships, add a Taxonomy term: Content with term
3. Add a contextual filter for Taxonomy term: Name
    3a. Choose 'Display a summary'
    3b. Choose 'Display Record count with link'.

Here is several resources that can help:
