Hello,

I recently installed Drupal's (9.2.6) contributed module Matomo and I see it on the administration->configuration->system->Matomo Analytics general settings and all.  However I need to get the Matomo site ID number to get started but Matomo support team said that I need to install Matomo 4.5.0 zip file from their download site that will give me the Matomo site ID.  What can I do -- uninstall the module and install Matomo into a Linux system and create a new database?  What is the best option to make things easier for me to install ?

Thank you.

Here's my code:
