Wrong file access with docker install

Hello,

I recently install xibo with docker on Ubuntu 22.04.
i can connect on web interface but when i try to upload a file i have an issue :
“The media library is not accessible in writing.”

I follow the docker guide installation step but i never find on this documentation a folder access config topic.

Someone already get this issue ?

Thanks for helping.

What are user permissions on your mapped library location ?

I have this

Does anyone have any idea about this problem?
