Create one more insert field in the event

How do you display the field like the target audience (this event is meant for), something like WHEN, WHERE, or one more block for Target Audience?
And also we use this plugin for our library website, and sometimes the event happens online also, I have explored but unable to find the location where I can mention the online mode information (event is online or offline, if it is online which platform (zoom, google meet etc..)with event links)
