Getting Send, Enter script on PS4 Remote Play to work?

[Hitosoyusan]

I'm new to this and was given a script that just presses enter every 30 seconds. However, it isn't functioning for PS4 Remote Play

#Persistent
SetTimer, PressTheKey, 30000
Return
PressTheKey:
Send, {Enter}
Return

Is the script. I'm running Windows 10 64bit and trying to get this to work for Injustice 2.
I've tried running it as administrator and changing send to sendinput. It works on every other application BUT PS4 Remote Play.

I am incredibly new at any of this, just wanted something to work while I was doing chores/artwork ;_; So any help would be very appreciated.
