Steps to follow:

Step 1: A speaker link is a unique link that the event organizer provides for a mapped speaker to join the event. Each speaker link is different and a speaker should not share his/her link with others

Step 2: If the event has started, then the speaker will get a special entry, click on "Continue" to enter the event.

Step 3: If the session hasn't started the speaker can go the session backstage or visit a different section of the event meanwhile, whereas as soon as the session starts the speaker gets pulled up automatically on stage along with other host and speakers. 

In the conference mode, the unmapped speakers have the liberty to join the event or hang out in the social lounge or explore the booth exhibitions (if any).
