HBO MAX & Hulu..

So I have Xfinity..duh.. and I also pay for HBO, Hulu, Netflix, Prime, etc..
I use HBO Max all the time through a Fire stick I have and with my cable box... Anyway...
Can I access HBO through Hulu? Like on the accounts page for Hulu I can "add-on" a service like HBO or Cinemax.. since I already pay for the service on Xfinity, could I use the Hulu HBO add-on without paying for it again?
Does my question make sense?
Thanks! ♡
