Using ZT with multiple accounts

I have 2 different accounts (work & home lab) & have created 2 sets of tunnels in each, with their own domains.

I want to run 1 cloud instance of a server that will serve applications for all domains in these 2 separate accounts.

I was able to set up a tunnel for domains under 1 account. Can some please help me as to how I can add domains from another account to this tunnel as well?

I’m currently running the cloudflared as a systemd in a linux box in the cloud

I’m new to this so a more detailed help will be really appreciated
