You are welcome brother. Happy to help!!!

Hi, first make sure the OWD setting of Lead object is "Private" then in your apex trigger add an if condition after the first "for loop" to check whether each lead's event description field is not null. The code snippet should look something similar like below: for(Lead newLead : trigger.new){ if(newLead.EventDescription != null){ for(User user : userList){ ..............// Leadshare instance creation } } } Please subscribe the channel if not done already!!

Hi, yes share object is available for almost all standard and custom objects. Basically its a junction object between sObject's record and user in this way for every record that is shared with any user there is a .shareobj record exists behind the scene.
