Can someone help me write a skript?

[GrenFlem]

I need help writing a skript that gives invisible players the glowing effect when they bump into another player. I've already written one that removes invis when they attack another player.

I'm trying not to loop something unless someone has invisibility to not lag things out, i dont want it to run unless it needs to

This code is untested but should do it.

every 1 tick:
    make all players execute command "{}check"
command /{}check:
    trigger:
        loop all players within 2 blocks of player:
            if loop-value-2 is set:
                execute console command "effect give %loop-value-2% minecraft:glowing 1 255 true"
