Can't open Anim Notif Modification Window

I tried opening the window in 4.13 and it seems to work, but for some reason, the window in 4.14 won’t show up…
Am I missing something?

same problem here… does anyone have solution?

Well… I just find out where it is…

Holy Molly, it actually really is there…really counter intuitive!

Thanks Kenaz for the info!
