Agentforce Coworker Context

Hello everyone, we are currently piloting agentforce coworker, some of my questions are  

1. how do I add context to some of the business terms we use?  

2. We have shared activities enabled, which means a single event can have multiple attendees which are kinda available in the eventrelation table, how do i make sure coworker is always looking at this table for additional context? 

3. are we able to modify the "Find" "Catch Up" and "Plan" 

thanks in advance
