How to clean cassette toilet compartment?

TravelPod

I am a new owner of a 2022 TAB 320 and wondering if there's a good way to clean out the cassette toilet compartment.  On my second trip out with the trailer, while I was out emptying the cassette toilet, my son had to urgently pee.  As you can all imagine, he made his deposit through the toilet and right into the underlying compartment.

Maybe I am wrong, but I don't see any drainage inside the compartment and I see some electrical wiring exposed as well.  Probably not a good idea to flush out the area with a garden hose.

You can’t flush out the cassette compartment with a hose as it will flood the interior of the trailer and the water will run underneath the kitchen cabinet. I have also thought about sealing the compartment and installing a drain. I am curious if anyone else has done this.
