Yes! As this is filed under 'Marketing' I assume you mean to prospective clients and not within Clarity.
Use Zoom or Google Meet (I don't like Teams). If you have more sophisticated needs that just presenting yourself/slides/screen then there are more sophisticated tools.
If you are B2B and it's a public session, create a LinkedIn event from a company page to collect email addresses (you can use Zapier to act on registrations (e.g. add to your mailing list or a spreadsheet for example)).
Make sure you record it (letting attendees know).
I hope that helps. Setup a call with me if you need to discuss further.
