Forced to use Action Link of Booking.com for my claimed activity on Apple Business Connect - I want to be able to change it!!

Hello! I'm encountering a very bad issue on Apple Maps / Business Connect.

So, I claimed my activity on Apple Business Connect (aparthotel/vacation villa, which is a properly registered as an accommodation business like a hotel).

I claimed the profile because I didn't want (and didn't like) that guests would be automatically redirected over Booking-com to book the accommodation.

I thought I could change the action of that button...

So, I claimed the page, I added more info and photos... and tried setting the very nice option of "Action link" button. I was already dreaming I could link my booking widget (simple link to open in Safari) to a "BOOK NOW" button... just next to my website button...

But, boy was I wrong!

My website is shown as before... ok: but I CANNOT CHANGE the Action Link!!! How come?

I'm being forced to use Booking-com integration!

There's no option for me to change it or modify it.

I attach a screenshot: you can see I can't remove Booking-com, and I only have that single action link available.

But, from Apple guides:

"...Action Links lead to developer-created experiences using App Clips, apps, or universal links that open in a Safari web view" > I WANT THIS!

More:

"These custom Actions can be delivered using the Apple Business Connect API by Third-Party Partners or Enterprise companies that have an app.

As a small business owner:

• By default, Maps preselects an action button for your Place Card if one is available >>> YES IT'S WHAT HAPPENED
• You can select which action button to promote on your Place Card, ****if more than one action button is available.*** >> apparently I only have that one, but why!?
• An Action can’t be deleted or modified; however, you can revert to the Maps default at any time. > how???

If you would like to remove an action button, you must contact the app provider directly to request an update. >>> I should contact Booking-com, seriously?

Is there something I'm missing?

I'm forced to being taken advantage I guess, and can't change the action link/button at all...

That doesn't seems right, since it's basically like Apple and Booking-com are taking advantage of these pins on the map... And I thought Apple created this Business Connect thingy to help small business owners :-/

Thank you in advance for any help.
