Runelite through osrs on steam issue

Sup gamers.Super new to Linux gaming after a brief stint in 2011-2012 with Ubuntu before I shorted my laptops battery by ripping the screen off (woops)

Anywho, I'm trying to run runelite through steam as old school runescape with the launch options: echo "%command%"; /home/zidane/Downloads/RuneLite.AppImage

First off, no idea what any of the options are doing and searching online is no help so I can't fix it myself...

But this is my problem... The game (runelite not osrs) opens briefly once, closes, and then opens a new runelite which I'm assuming is making steam no longer think that it's running old school RuneScape? I'm able to play but I want steam to know I'm playing so number go up on steam while number go up in game.

Edit:opening both the RuneLite.AppImage & RuneLite.jar does the ol opens and closes and reopens itself again... And I have read/write + execute as program enabled... surely I messed something up?

    
opens closes and opens runelite
echo "%command%"; /mnt/Games_Linux/RuneScape/RuneLite.AppImage
