i dont use essentials but i use AFKPlus to record afk player

Describe the solution you'd like
AFKPlus has extension named AFKPlusPAPI that enable placeholderapi for afk player

in the AFKPlusPAPI config i can set placeholder output for afk player and non afk player

i want to use this output for sleep-most plugin to detect the afk player like

set-afk-placeholder: %AFKPlus_Status%
placeholder-is-afk: "True"
placeholder-is-not-afk: "False"
