I solved this week's challenge by taking inspiration from Google Forms. I recreated a theoretical application called "Slot-Able" which helps the user to create forms and responses in form of time slots.
The user, if he is mentor, will choose and customise time slots based on his availability, and then send the link to his mentee through the required platforms.
The mentee, on getting the link, will respond to the teacher by choosing the appropriate time slot and sending a message if needed.
The mentor can check the application for responses, and it will show the number of people responded to that link, as well as those who not responded and the total links sent.
