Hi,

You can check the documentation or rst file of the module to see if there is something that can help. I can that you already have logged a ticket in corresponding repository: https://github.com/OCA/vertical-hotel/issues/196

Hopefully some one will respond for the same there and in case if you didn't receive any feedbacks, try pinging/mentioning some one who contributed to the module in recently:  https://github.com/OCA/vertical-hotel/commits/15.0/hotel


Thanks
