How can I use the Sketch Theme if drawio is running via Docker?

[dd-fxaver]

Dear all,

I've been using drawio within a Docker container, but I'm struggling to apply the Sketch Theme to the interface. I've checked the environment variables and settings but haven't found a straightforward way to activate this theme while running drawio through Docker.

Could anyone guide me through the specific steps or configurations needed to enable the Sketch Theme?

Version 22.1.17

I've used the following docker-compose.yml file:

Thanks in advance for your assistance!
