Getting values for a key in CSV using infinity plugin

Below is my CSV data -

"Venue","SetupName","GNBID"
"ABC","ABC_1",1
"ABC","ABC_2",2
"XYZ","XYZ_3",3

I want to have two variables “Venue” and “SetupName” in grafana, where “Venue” should have dropdown “ABC” and “XYZ”, based on my selection in Venue, “SetupName” should update. I am using infinity plugin and csv file, tried using UQL as well, but unable to do so. Can anyone help?
