Activation

Hello,
I own win 10 pro for workstations and a win 10 enterprise LtSB- I made the mistake of installing the win 11 enterprise N thinking it was Enterprise LtSB and now I can’t figure out how to authorize without a wasted day. Installing windows 10 enterprise and then installing win 11 from there. I saw there’s ways but I got lost in the adv install and all the options. Please help-
