Currently, when another player opens or closes a gui and subtitles are enabled, "Chain armor jingles" is appears, when the other player clicks their screen "Chicken plops" appears
Due to those subtitles being misleading, a Sound Event should be created for those occurences with more accurate subttiles, for example "Player opens menu" or "Player Clicks"

Looks like I'd have to go well out of my way to register my own sounds just to adjust the subtitle since I'm just using vanilla sounds, adding more maintenance / porting costs to the mod, will avoid for now.
