Bosch SX Chainring Replacement

Total noob question here — I've never changed a chainring on any bike, let alone an e-bike. I have a 2025 Transition Regulator SX that's due for a new chainring, (i think) I've got the correct replacement chainring. 

Before I dive in, I want to make sure I understand the specifics of the Bosch Performance Line SX setup so I don't mess anything up. I couldn't find any Regulator-specific videos or guides, so I'm hoping someone here can fill me in. I did email Transition directly but they wont be able to get back to me until monday, apparently they are on a company outing of some sort. I wanna go for a rip this weekend so im hoping to have this completed long before monday haha. 

My main questions:

• Reverse threads? I know some e-bike motors use reverse-threaded parts — what's the deal with the SX?
• Process? Any specific disassembly/reassembly order I should follow?
• Spacers/gaskets? Are there any spacers, O-rings, or gaskets I need to watch for (and not lose)?
• Chainline? How do I verify I got the chainline right when reinstalling? Any room for error here?
• Tool specifics? Any special tools beyond the Bosch lockring tool and 8mm Allen?
• What else? What am I not thinking to ask?
  
  Thanks in advance for any help you might be able to offer!
