Your mentor will suggest times for your first digital meeting. If you can’t make any of the times, you can easily let them know.
Once you’ve settled on the time, either the mentor will send you a calendar invite, or you will get asked to send one. If you are unsure, just send them a message.
If it’s been a few days, and you haven’t received any meeting suggestions, feel free to Nudge your mentor, or send them a message.
