Is chat history for embeds available only for PRO plan ($116/month)?

I saw that another coach uses a Pickaxe embed in his coaching platform (not a Pickaxe studio). And chat history is saved there - I can access my chat even after a couple of months. But as a Pickaxe Lifetime license owner, I can’t find a way to make my embeds show history for each user. Do I have to start paying $116/month for PRO plan to have this opportunity or is there a more budget-friendly way? :sweat_smile:

In the embeds the chat history is available on all level of accounts and is in the upper right hand corner.
