How does keep track of changes to the data work? How can we view historic data

[LyonMNGIS]

Hello,

I have a couple questions regarding the option in AGOL to keep track of changes to the data field (add, update, delete features).

1. Is the purpose of this function to archive changes to any AGOL hosted feature layers?
2. Can we view any changes (including deletions) in ArcGIS Pro?
3. I noticed I cannot turn keep track of changes to the data on or off in the settings menu.  This is true even if I turn editing off.  Why is that and how can I turn keep track of changes off?
4. Is there anything else I need to know about this function?

Thank You!
