SMS notification

Hello,
I’m willing to use your plugin for one of my clients, but he has a SMS account with OVH and does not want to use another one. So, I would like to know if it could be possble to use the OVH SMS acount instead of your own solution, and if yes, what needs to be modifiyed in order to go with this solution.
As OVH SMS could be sent thanks mail, we can chose to modifiy the Bookly SMS notification, or add a specific mail notification that will send a mail to the OVH account with dedicated details in it.
Thanks
Pat
