About the expansion pack

First of all hello. I have a question, friends. I bought Diablo IV on Xbox when it came out (before gamepass came) and I have been playing for a long time. I bought the expansion pack on Xbox, but I cannot access the character and map. That is why I returned the pack I bought. Now my real question is, if I buy the pack on PC, will I also be able to access it on Xbox? I apologize in advance for the translation.
