Compatibility for Pluginhive Woocommerce Bookings and Appointment

Hi

I use Pluginhive Woocommerce Bookings and Appointment and would like to edit the email sendt from this plugin.

The emails shows up on Woocommerce -> Settings -> Emails but it is not possible to costumize the emails.

Is it possible to add compatibility with this pluing?
