Where are the migration files?

Ok, I found the generated module under the temporary folder. [site_root]/tmp/eme/.

1. I then moved the eme folder to the new site's [site_root]/web/modules/custom/eme/
2. I had to adjust the file permissions to 644, otherwise the site crashes with a permissions error.
3. Now the module ([migration_ID] Entity Migration | Generated with EME module) shows up in the Extensions page
4. I enabled it.
5. checked that Migrate, Migrate Plus, and Migrate Tools modules were installed and enabled.
6. Tried to run drush migrate:import --tag my_project_dev --execute-dependencies but got the error:
   

   [error]  No migrations found. 
   [error]  Message: Failed to connect to your database server. The server reports the following  
   message: /No database connection configured for source plugin variable/.                                                                                    
    * Is the database server running?                                                                                                                          
    * Does the database exist, and have you entered the correct database name?                                                                                 
    * Have you entered the correct username and password?                                                                                                      
    * Have you entered the correct database hostname?
   

   
   
   I think this didn't run correctly because I used the module name and not the tag name: Example: using 'community_content' from community_content.info.yml when the tag name (located within that file) is actually 'community'

7. Running it with the proper tag name did run a migration, but nothing was Processed (0 created, updated, failed, or ignored). Running individual migrations also fails to import anything

Any insights would be helpful.

If possible, it might also be helpful to post a video on YouTube of all the steps of creating an export and then importing an EME migration to a new site.
