Trying to recover lightning channels from an older Umbrel to a new download

Specs of my set up:

Node - Dell Optiplex 3080 with 1TB SSD, installed Ubuntu 22.04 LTS, I followed the instructions from the umbrel site to install onto a Linux machine.

Main PC- Windows 11, Brave browser, I connect via ssh.

I’ve re-downloaded and synced the Bitcoin blockchain, and now I’m installing the Lightning Node app, but cannot recover with a seed phrase, I’m given a new set of words to save.

I have my previous Umbrel’s channel.backup file saved to my Windows PC (I used WinSCP).
I need to recover my previous LN channels onto this new iteration of Umbrel, but cannot seem to figure it out.

I’m fairly comfortable to using command line.

Please and thank you.
