LI connection messaged me thinking she met me at an event, how do I play this?

I've been adding a lot of people on LI with investor relations roles. I've cold emailed this particular connection via email twice and she hasn't responded. Yesterday, she sends me a generic LI message saying "Happy Tuesday! It was a pleasure meeting you a few weeks ago at the NY Common Emerging Manager Conference. I'd love to get on a quick call to discuss synergies. How does your availability look in the coming weeks? Thank you and I look forward to hearing from you soon."

When I respond, do I correct her saying oh actually this is a mistake but i'd love to connect or do I schedule a call and get her on the phone to do a coffee chat? I'm not sure what synergies she's thinking of considering, she's opened by emails (boomerang tracker).

TIA for the responses.
