I have observed this Page Context Dropdown available in flow action so why do we use it?
P.S. Screenshot Attached
Page context is the one where we can use the section from that respective class. Let say if the flow action is in data class and want to display the section from work class then we can use the page context option in the flow action rule and give the pyWorkpage. Then you would get the autocomplete to choose the section in the work class.
