Cannot use AI addon even if I have a Pro license

[cyberzork]

The AI Add-on “is extra per month with a One-Time Payment” purchase. Its only included with a Subscription as per @Gary post below in the following thread.

"AI Add-on" / "Extra AI Credits"

AI is included only with a subscription license. For all other licenses, you will need to purchase an AI addon if you want to use that function. It is a monthly subscription which allows you to generate about 300k words using the AI. It is unlikely, but if you exceed that in a month, you can purchase extra AI credits for another 300k words.
