I can't change the font size on the interface

[Shinusagi]

Hello, I just installed the latest Docker image for Part-DB, it is my first try on this application but I can't change the default font size of the UI, it is HUGE, and if I reduce the webpage zoom it is still big but the left lateral panel becomes even smaller.
I would like to have the same font size as the left panel in the whole interface but I can't find the options to do so. I tried changing themes and the result is always the same, the color changes but not the size of the interface.
I tried searching on the env file and other configuration files and couldn't find anything related, so please I ask for help here.

After further research helped by the AI I found that I was looking to change the "body-line-height" mainly instead the font size, it seems to be at 1.5 and I would like to change it for at least 1 or 0.8 which I achieved with the browser editing the css code at least temporarely to check how it was. But I can't find the css files on the docker version to edit and I would anyway some more guidance about it since I never in my life did it before and I know I will mess something if just going with Ctrl+F and replacing values on the config file... please.
