Serious question on HIV test

I recently had a high risk exposure (condom broke) while having sex with girl (who I met on social media). doing some reach on all different types of test... Here is my serious question and would request expert feedabck

I know there is the 4th Gen Ab/AG test that most experts say is conclusive at 4 weeks some say 6 weeks. I checked on CDC they also say its conclusive at 45 days. This test checks for P24 antigen and Hiv1-2 antibodies. All other antibodies test are conclusive at 90 days..

So the question I have is since 4th gen only checks for HIv -2 antibodies why its deemed conclusive at 6 weeks when ONLY antibody tests are conclusive at 90 days?

P24 antigen is only for HIv-1 NOT HIV 2

It is not necessary to study biology to prevent hiv transmission, just as it is not necessary for you to know how an X-Ray machine works when a doctor tells you if you had a broken bone. All you need to know is the duo is conclusive. We rely on experts that 4 weeks is conclusive, and do not pay attention to whatever other sites people locate or we will be here arguing all day about how many weeks it takes to be conclusive.
Not challenging experts will will be good to understand scientifically why 4th gen ag/ab test is conclusive for hiv 2 when it's only testing for hiv 2 antibodies while all other antibodies test have 90 days window period.
One reason could be low prevelance of hiv 2 in society just guessing
