Calling someone into a conference call

A person to join our conference call will be driving and would like me to call them into the conference. I don’t see an option for this, am I missing it somewhere? Thank you !

Please check if you have option “Invite by phone number” in the Invite section in the app.

I did not see that in the app for Android or for Windows desktop. In the copy invite there is a link to call you into a meeting, but I don’t see a way to enter a phone number and invite someone into the conference call as you suggest. Thank you for your prompt response.
