Where is the Disney+ Channel? The 3 part Beatles "Let it Be" is supposed to be on it in Nov 2021 and Dec 2021.

I am desperate to watch and record the 3 installments of the "Let it Be" film by the Beatles that is supposed to air on Disney+ sometime this November 2021 and December 2021. I cannot find Disney+ on any cable line up through Cox. I have several Disney channels but no Disney+. Does anybody know anything about this? If Cox doesn't offer that channel that means I won't be able to see something I've been waiting decades for and I swear I will switch to another provider that can offer all the channels that everybody else seems to have. . I pay a fortune for this service and expect more channels to be available.
