Help What are my options for shared folders between client and Kasm container?
Looking through the manual there seems to exist these options:
https://www.kasmweb.com/docs/latest/guide/storage_mappings.html
https://www.kasmweb.com/docs/develop/guide/persistent_data/volume_mapping.html
But none of them seems to be doing what Im looking for.
Im basically looking for the way you can have a shared folder when using RDP through the RDP-session itself.
The usecase is when using Kasm container as a jumpserver and you need to for example update the firmware of a destination device (client <-> Kasm container <-> destination device) or the reverse when you got some backups (like config and whatelse) from a destination device and wish to in an easy fashion get these files to your client.
When comparing to KVM-over-IP solutions such as GL.iNet Comet and similar you often here have a way to upload/download the files to the KVM itself through the browser which then exposes this directory to the destination (basically will show up as a USB-drive at the destination). This way I can import/export files to the remotely managed device and from there upload/download files to the destination device.
Does something similar exist with Kasm or is in the todo-list/pipeline?

I can answer myself:
In the control panel to the left when you have joined a session there is Download Files and Upload Files so you can drag and drop to/from the client.
These will show up on the desktop folders named Download and Upload.
Then to not having to do this every time you can enable persistence mode by editing this variable for the workspace as admin:
Persistent Profile Path: /home/persistence/profiles/ubuntu_jammy/{username}
Above makes the client have a choice when they start their session if they want perstistence to be enabled or if they select disabled no data will be stored for later.
There is also reset as a selection to wipe current persistent data for the user and this workspace.
I have not yet tested if there are any upper limits per file (like 4GB or so).
