Can't add write permission to docker volume in docker-compose

Question

Issue

My main goal is to create a wordpress container on my linux machine for development on that container.

Therefore, I'm creating new volumes for the plugins and themes folders and even add read & write permissions, with the :rw option.

However, when I'm trying to create a new directory or file in those "volumes", I get an error message (especially in VS Code), that tells that I don't have the permission to add these volumes.

Moreover, the permissions based on the ll command shows that the owner is the only one with the w permissions. It means that I cannot use the group www-data and add it to my user in order to edit those volumes.

When I'm trying to run chmod 766 themes plugins, the volumes are not bind anymore, so this solution doesn't work.

I've searched the whole web (including stack overflow), but none of the answers didn't work for me, so I'm lost :(

Here are some details that can help you with finding solution, including the docker-compose.yml file.
