Steamdeck - DeadSpace 3 Steam Purchase - OfflineMode Origins App

Hi Guys,

I have Dead Space 3 on EA Origins, and I played this over 9+ years ago on release.

I recently re-purchased Dead Space 3 again on Steam store for 19.99 to play on my SteamDeck.

Installs without issue.

EA Origins installs too (yikes,) and prompts for logon (big-yikes.)

This all worked fine except there's no official controller support, (big-freaking Yikes.)

I carry-on, and configure Mouse/Keyboard as best as I can on SteamDeck

1- Playing the game on my home network is fine, it auto-logons after the first time.

2- If i take my SteamDeck on the go, I can't play DeadSpace 3 at all, EA Origins will prompt for sign-in and without internet connection (again, on the Go with Steamdeck,) this process fails, and the game- auto-closes from Steam?

Its 2022, this game is nearly a decade old, is there NO WAY to set the game-launch options on Steam to tell EA Origins to chillout and let me play the game offline?!?!?!

Please help, I just played through Dead Space 2 on Steamdeck a day ago and this sucks so much that I re-bought a game i loved only to be hampered by oddly enough, online DRM.
