Help identifying leaky part name and any suggestions (Intex PureSpa ssp-h-10-2)

Unfortunately I have never seen one of these.
If I had to guess, the screws mount the heater tube to the bulkhead, near side having a flow switch, sensor, and ??? drain plug, or perhaps a thermowell for a high-limit. The pics make it hard to see under there.
The bulkhead will have a gasket/o-ring, and may just need a little tightening of the screws if leaking there. Go in a criss-cross pattern, not a circle.
If that's a drain plug, remove it and see how it seals. It may have a gasket/oring, or it may be a tapered thread with teflon tape. Repair appropiately but DO NOT OVERTIGHTEN a tapered thread as it will crack the drain fitting in the bulkhead. If the repair does not work, it may be a cracked drain fitting.
Better pics of the leak and all around, and a wiring diagram if you've got one, would help alot.

Note I do not have nor have ever owned a hot tub but did some poking around...

Found this which might be a better angled picture: There is a single reply linking a YouTube video:
While the video is that of a different pump it leads me to suspect the leak might be from the piece with the sticker on it no sealing/being seated properly. If your handy I would do what the guy in the video did and just start digging in and go through the process of elimination.
