How best to link PC account to PS5 account, so I can play PC characters on PS5?

Hi everyone! I am from Singapore (Asia PSN on PS5).

I have a PC account (This account I am posting from) for POE1 and POE2, I want to play this account on my PS5 as it has tons of MTXes and stash tabs.

On PS5, I have an account on NA PSN. POE1 is only launched and available on NA PSN store and not other stores, e.g. Asia PSN (Where I am from). So I downloaded POE1 from NA PSN, played that and bought MTX.

On PS5, I see POE2 now available on both NA PSN and Asia PSN. Which means I can now play POE2 on Asia PSN on PS5, if I buy the early access. Point to note is, I can play POE1 on Asia PSN too, which I download from NA PSN, but the MTX store is not working on Asia PSN which it is not launched under.

Questions:

1. If I want to connect my PC account to PS5, should I connect my PC account to NA PSN or Asia PSN?

2. If I connect PC to NA PSN, I can play my PC characters when I am logged into my NA PSN on PS5, but that is not my main PSN. If I connect PC to Asia PSN, I can play PC characters on POE1 (Downloaded from NA PSN) on my main Asia PSN, but I cannot buy points or MTX on Asia PSN. But can I continue to buy points and MTX on PC account via PC, and still use them when I play the PC account on Asia PSN on PS5?

3. I have POE2 access on PC account. On both NA PSN and Asia PSN, I need to buy a $30 pack to even download the client onto PS5. I don't want to do that because any funds I put into the game, it should be on my PC account. Is there any way to play POE2 under my PC account on PS5? Or I need to suck it up and buy POE2 on either NA or Asia PSN, then not ever using that account any more, download the client and link my PC account to play?

Any advice will be much appreciated! Thanks!!
