Hey, the game was only bundled twice and it used to be true if you or someone got it in the 2020 bundle, but it was changed after the invasion. See steamdb page of the game, scroll down to Packages that include this app. You can see the normal sub is restricted. Exact info here. For games that have many subs, you can check with this member's posts, as restrictions are often mentioned at the top, especially for Humble bundles.
