Wordpress upload dir

Hello i made a custom plugin that point the wp-content/upload folder to an external object storage (s3 compatible) to serve images over cdn.mydomain.com

What i noticed is that matomo also install files inside the upload dir of every subdomain (this is a multi-site wordpress).

I need to know if it is ok tu serve also matomo over the cdn or is it a problem? i’ve seen there are also php and .htaccess files there that can’t work over s3.

see the picture:

if it is a problem, there is a system to install those files in a separate dir than uploads folder?

Thank you very much

Nobody can help me with this?

Just to confirm, are you trying to integrate this custom Plugin with Matomo for WordPress? Are you able to provide more insight on what you are trying to achieve please?
