Inverter Coolant Low - Take it in still after filling?

Our 2022 Prius threw an overheated hybrid system error last night. I thought it was the cooling vent being blocked by a bag, so I clear that/cleaned it and disconnected the 12v to clear the code. It came on again today during a short test drive, and I realized the inverter coolant is low (shame on me for not checking that first...). It's also throwing a Hybrid System Malfunction error now (doesn't say anything about overheating).

I'm going to fill the inverter coolant today, once I do that should I disconnect the battery to clear the codes again? Or still take it in to the dealership to have them clear the codes/look at it? If I don't take it in, I know I'll also need to check the coolant level like a hawk to make sure there's no leak.

 

Thanks for the reply. The code it's throwing is P0A01 (voltage converter coolant temp sensor - circuit range/performance).

edit - I also noticed a large number of leaves and fluff in the car on the floor under the engine bay, so maybe that’s from mice? I’m not sure if that’s new or not, I admittedly don’t look under the hood as often as I should…
