arraystring (<string>, <delimiter>)

The arraystring() function returns a string from an array, where each array element is joined by a defined delimiter.

Retrieve all action_app_id_transitions that are not null, combine each array into a string where array elements are delimited by " : ", and then use dedup the resulting string.

dataset = xdr_data 
| fields action_app_id_transitions  as aait 
| alter transitions_string = arraystring(aait, " : ") 
| dedup transitions_string by asc _time 
| filter aait != null
