Review suspended for new App (Requires Shopify Flow)

Hello, my app was 3 times in submission and is suspended for some days now.

I dont understand the problem, cause the schema is like our other Apps (which are all approved on the App Store)

App ID: 387212410881

The reviewer told me:

“The application is requesting to download other application for it to work, which is prohibited. See this screencast for reference.”

We have 3 Built for Shopify Apps and try to be conform to everything but it is kinda frustrating here.

The App which is required is Shopify Flow. (We are adding a new action with our new app)

Can you help me out here? Is this a new guideline?

Or is it not allowed to show a third onboarding step on the dashboard to install Shopify Flow?

Thank you
