Some app directories are owned by a different user than the web server one please

hello, I come to you in particular on this post because I have a similar concern I am a beginner in the Unix world, I installed nextcloud under docker, nextcloud tells me this

  • Some app directories are owned by a different user than the web server one. This may be the case if apps have been installed manually. Check the permissions of the following app directories:
    • /config/www/nextcloud/apps/activity
    • /config/www/nextcloud/apps/admin_audit
    • /config/www/nextcloud/apps/backup

you were talking about the web user but I don’t know if you are talking about the server admin user or another user, if it is another user or find it. Could you please help me
