Questions about licenses

[FarOutlier]

So, I bought a license for Sublime Text 4 and added it to my application. Great so far.
Getting used to Sublime Text 4 and frankly, I love it. Liked Notepad++ but this is much better.
Now I want to build a home server on a junk computer I have. Naturally I want to use Sublime Text.
So, can I use my license on 2 computers? I think I can, but I am not sure.
If I can, how do I recover my license so I can put it on my server build?
I am usually pretty good about saving stuff but I cannot find that license. I vaguely remember it. Sublime has my license documentation. So, where is the license kept? Maybe in an email? In my app?
I backup important data and run sublime from a USB. Is it possible to just use a copy of that USB to run Subline?
To address your thoughts? Why yes, I do NOT know what I am doing.

From the buy page:

One license key is all you need for all your computers and operating systems

Your license was emailed to the address you used to make the purchase. You can recover your license here: https://www.sublimetext.com/retrieve_key
