I must admit I can’t find the exact guide I used anymore. Especially not a English one.

But the official guide should help you: www.zabbix.com/de/integrations/proxmox

I think whatever I used was pretty close to it. If you have any issues send me a DM.

(And tbf, I use both the Agent2 and the API in a perverse mixture. And for some nodes IPMI on top of it. It’s really kinky,but it does the job)
