Hi @Oumeima,
how did you manage to install your package in the app? Did you have to employ any tricks to get the volume to show up in the app?
Currently, I am trying the same but installation fails whatever I try because the mount point for the volume inside the app does not exist.

ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: '/Volumes/catalog/schema/dependencies/package_name-1.0.0-py3-none-any.whl'
Processing /Volumes/catalog/schema/dependencies/package_name-1.0.0-py3-none-any.whl (from -r requirements.txt (line 50))
WARNING: Requirement '/Volumes/catalog/schema/dependencies/package_name-1.0.0-py3-none-any.whl' looks like a filename, but the file does not exist

Thank you!
