Let Customer Connect Their Hubspot

I’m decent with Bubble, but low experience in code (outside of some very low code builds). I’d like to make it so my customers can log into Hubspot on my Bubble App, and link data from my app to their Hubspot.

The Hubspot plugin only seems to allow me to connect my Hubspot, but can’t connect others. Any ideas on how I can let customers connect their Hubspot accounts?
