I know how to change the watermark logo but how to remove it?

so I know in order to change the watermark logo I can change the docker-compose.yml file like this:

    - ${CONFIG}/web:/config:Z
    - ${CONFIG}/transcripts:/usr/share/jitsi-meet/transcripts:Z
    - ./customlogo.png:/usr/share/jitsi-meet/images/watermark.png

However, now I am wondering how to remove it? I could not find what I could have written instead of the picture path. Thank you.

I think just delete or rename watermark.png file
or use css to display : none

How to do the css thing?
