Build an online appointment scheduler

I am looking for a scheduling tool on my video interviewing platform where recruiters can schedule an appointment with prospective candidates in their own time. The features I require are simple - 1.Email Reminders & Confirmation
2.Ability to cancel and reschedule
3. Auto Timezone detection

Basically it's something like Calendly. I need it to be integrated on my website. My website is built using Angular 10.

1. standalone tool that can be used on my website? no subdcription with third party required?
