Cant's select an element to launch a custom bot. Error message: Could not generate a selector. Please add your selector manually.

I'm trying to add a custom bot which needs to be launched by clicking a button. When I try too select the element on the website, it keeps throwing up the error: "Could not generate a selector. Please add your selector manually: (Error: Selector was not found.)". This is despite the element having the attribute:

<a class="bottom-price-btn theme-btn-2 btn" data-intercom-target="Get in touch">Get In Touch</a>

Any ideas how I get this to work?
