There are 4 "all.css" files. Why and which one is the working one? Trying to remove logo, Docker

Hello,

I am trying to remove the upper left logo in Docker. I heard that I can change the “all.css” file but there are 4 of them.

When I do sudo find -name all.css this comes up:

./var/lib/docker/overlay2/1216d6be60d12c642c0c1b89d9f3ea1cb358bef9cefa0e9867f3c1a5ba4ecc6c/diff/usr/share/jitsi-meet/css/all.css
./var/lib/docker/overlay2/c62fdb89ac7e3322df71769759d0da55c4975c853cef000b90cf520d77030aa9/diff/usr/share/jitsi-meet/css/all.css
./var/lib/docker/overlay2/6dca9616c4ce2fb9c42c5f5b82baad288d66d12abeb93e1ec0b1d93159e4df03/diff/usr/share/jitsi-meet/css/all.css
