Confirm booking request

Hi there, since the beginning we've set up our listing at Booking.com platform

we're getting instant bookings without a need to confirm it first. We understand it can be great feature for our guests, but sometimes it's a bit restricting and very surprising (with very last minutes booking) someone can book in without our need to confirm it.

I hasn't been able to figure out where to change the booking style from the instant to the one which would need a confirmation to become a valid booking.

Any idea how to achieve this?

Many thanks,
