Can't Update Grav - Webserver-Configs Permissions Denied

Hi there - I recently moved Grav (v1.7.9) to a new Lightsail Apache server on Debian. Since then, I’ve fixed many permissions issues, but cannot figure out the last one.

From the admin panel, all of my themes and plugins update correctly. However, when I try to update the Grav version itself, the following error appears:

“Grav update failed rmdir(/opt/bitnami/apache/htdocs/grav/webserver-configs): Permission denied”

Here are the Webserver-Configs permissions on my server:

drwsrwxr-x 2 bitnami daemon 4096 Apr 8 00:34 webserver-configs

I tried both owners as “daemon daemon” and “bitnami daemon” but neither seem to work. These are the same permissions as the cache and user (both working) directories. Any ideas?
