How to remove square channel balances from windows?

Question

Figured out how to remove window by pulling out metal tabs on side which catch channel balance and then removing window by tilting sideways. Looking for advice on how to remove channel balance, I know it must be something simply but I don't want to mess something up. I don't know if their spring loaded, etc.? Thanks for any help!

Answer 1

used to be pins that would pull down from the bottom of the operating/moving portion of the window
