Help with installing the game (xbox series x/s)

(I'm on the xbox series s)

Hello, I played this game since it got released on my ps4, with time I moved on but recently I kinda missed playing a good cod and I remembered this one so I went right to installing again and enjoying it all over again

I have a friend that have that game so we shared accounts and I installed. At first, as I started the download I noticed that On the queue list it showed only the base game and not the add ons I remember that was required, "OK maybe it doesn't needed anymore?" But when I finished and launched it on the main menu of the game instead of showcase a "Play" button it said "purchase" on it, but from here it just got more complicated bc I went to the install list on the account settings and tries to install the add ons there, I managed to install all of them besides the "multiplayer pack 1", it won't let me at all it had an error massage.

The thing is even after all of that it still said to me that I need to purchase the game even with the facts that all the add ons are installed and there, I looked up a bit more and found out that alot more add ons are required and supposed to be on the install list on the "manage game and add ons", but the list I'd empty completely, Something appeared in there just only I installed the add ons inside the account install list, but the other ons are not there and The options to even click the multi or the camp or even the spec ops are not there, just the purchase option like I don't have the game. Can someone help me?? Thank in advance reddit.
