ISSUE ADDING NEW COMPUTER TO TEAMS ACCOUNT

I'm having issues adding a new computer to my team. I followed every step in the instructions. I can see the Teams account on my Jump desktop connect however when I'm in my teams dashboard the computer is not an options to give people access to. when I was initially setting up I did delete that computer off the Teams account by mistake after it was done doing the migration process but I should be able to add that computer back to the account. Can someone help me please. this is urgent as i'm in a middle of a big project.
