Which guest permissions are needed Commerce Donations

Hi folks,

I'm setting up Commerce Donations after setting up Stripe and PayPal, haven't added Subscriptions yet and I'm wondering which Commerce App module permissions guests should have access to in order to be able to donate as a guest.

The Help guidance page doesn't cover permissions.  Some of the app permissions seem to add an empty drop down to the menu when enabled for guests to access, with an option called My Details, which probably isn't right for guests and bots to see.

Many thanks
