You will have a choice to use Continue with Google, Continue with Outlook, or log in with an email address.
You will see the Loom icon appear in your extensions and you can begin your recording from there.
What I think is a really nice feature is that Loom appears in your Gmail (when you select Compose in Gmail). When you see the icon appear, select it, you will then have the options to use the most recent recording, my videos, or create a new recording. If you choose create a new recording you will then be prompted to select Loom in your extensions. You will then select be able to record webcam, tab, or whole screen.
