HomeToGo, when it comes to creating bookings, HomeToGo creates leads using POST v1/leads.

You can see all three fees in the quote as they are all mandatory (Optional: No).

The logic of creating orders is that we take all mandatory fees and apply them to HomeToGo order.

Adding a "Fee: Apply to HomeToGo" option in the Fees setting is needed so other channels' fees would not be added to HomeToGo.
