Quoting the docs: Record Events
Tip: You can add custom parameters to Standard Events so you don’t have to create other Events if you need custom details on Standard Events.
How do I do this? I don’t see an obvious way in the Event Manager.
Hey Krystal,
I’ll raise this with the team, it sounds like the documentation might be out of step with the behaviour here.
Will update you with what I find out!
Update to the above:
Yeah that looks like old documentation from an earlier stage in the Beta.
Standard events are consistent accross all projects, so you’d need to create a custom event if you wanted to move away from that.
Thanks for spotting it, we’ll get the docs updated to reflect the current design
