Add meta tags on a page generated by a custom module I am trying to modify the meta tags of one of the pages of my web. For example, I want to change the title, the description and add the robots tag.

I have tried using the token and metatag modules to change this, but it is too generic and I do not see the option to change it individually on each page.

Also keep in mind that the page on which I want to change these tags is generated by a custom module: creating the Twig manually and generating the URL by routing.yml. There's the problem, that by not generating by the back, it does not recognize it as a page.
I've tested successfuly Metatag Routes module for Drupal 8. The module adds a button in the default metatag dashboard page. The user can configure metatags for custom controllers generated by code.
