Installation path of immich (installation via Portainer)

[chriswa81]

I have a question about restoring the database. I have understood the documentation from immich so far. It says that you go to the immich installation directory and execute the code lines for restoring the database.
Now my question. I have installed and run immich via Portainer using Stack. Now the question is, where do I find the installation path where I have to execute the commands to restore the database?
I hope you know what I mean.
