Your personal link is where clients see everything they need to book with you. Your work, your prices, your upcoming availability and a way to send you an enquiry, all in one place. The more it's out in the open, the fewer conversations you're chasing across different apps.
Add it to your Instagram bio, pin it in a post, and keep it somewhere easy to find in your story highlights.
If a client wants to have a chat first, that's fine too. Plenty of people like to ask a few questions or get a feel for your work before committing to anything. Let the conversation happen, then when they're ready to move forward, send them your link to get the enquiry started properly. That way you still get the details you need even if the conversation began somewhere else.
The more clients you point to your link, the more of your bookings you can manage properly, all from one place.
