Drupal 8.x

I've have used "Upgrade Status" and checked that all the requirement are met and all my modules are compatible with Drupal 9.

Then I followed the steps found in the documentation. First I issued the following commands:

chmod 777 web/sites/default
find web/sites/default -name "*settings.php" -exec chmod 777 {} \;
find web/sites/default -name "*services.yml" -exec chmod 777 {} \;

Then I issued the following command:

I tried using hooks but  in $view->result variable I only get nodes from the actual page (10 nodes because pager size is 10). My view has multiple exposed filters so I want the resulting nodes from filtering

My ultimate goal is to create a link in that view with concatenated nid argument. Is it possible?

I would like the ability to click on a map marker and the details for that node to be opened in a block, similar to:

Any thoughts regarding the best way to achieve this would be appreciated.

I've built a few sites using Drupal 7 and recently Drupal 8.9... in progress. I'm completely new to Composer, though, and it's apparently a big deal now. It's apparently required in order to use the upgrade status module to figure out if my site's ready to go to Drupal 9.
