What is best way to convey to a user that two things are necessary to utilize a feature?

We currently have a feature that allows users to add a Donate form to their page, but this feature is disabled unless you do two things:

  1. Upgrade to a paid account
  2. Connect to Stripe

We want to enable this feature in Free accounts to allow the user to try using the feature before they decide to upgrade. Publishing the page is restricted and is only possible after upgrading.

Here are a couple ideas I explored:

Idea 1 - A notification banner above the Donate form that says, "You cannot publish this page until you upgrade your account. A Stripe account is also required."

Idea 2 - Add a notification banner above the Donate form that says, "You cannot publish this page until you upgrade your account." Once upgrade has been completed, another notification about Stripe is introduced.

The problem with Idea 1 is I feel like having two actions in a notification might be a bit much. It can also get quite wordy.

The problem with Idea 2 is Stripe isn't available in other countries. So it would be upsetting if you upgrade only to find out afterwards that Stripe isn't available in your country.

Any other suggestions? What is the best way to convey these two points?
