Mac Mini M1 Recovery Partition accidently deleted.

Sooo I was messing around with an external usb drive and thought I had a partition on it that looked like I had unused free space I could reclaim.

Foolish me though was actually looking at the wrong hdd and removed what I now know was the recovery partition of my internal drive (See attached image, there used to be 3x partitions on this drive.).

I have looked around the web and can't find how to revert that change.

Do I resize my data partition and reclaim that space, somehow downloading the recovery image and "reinstalling" the recovery tools onto the recreated drive or am I now stuck having to create an external usb recovery image anytime a new OS comes out?

Mac mini 2018 or later

If you do have have a backup? Use Time Machine or Manually move your user files to an external drive.
