Calling or chatting via FaceTime with Android is as simple as sending a web link to join the call. You approve anyone who tries to join the call via that link, to lock out strangers.

Anyone who has the link can click it, enter their name, and request to join the conversation. As the host, you approve everyone who wants to join by tapping the green checkmark button.
