Can people im gamesharing with see games ive gifted to another account?

By gameshare I mean they would log into their account on MY pc. And Im fine to do that theres no issue security wise but this is an alt account that I have gifted a game to and have played some stuff on this account I dont want them to know about. They wouldn't be logging into my account on their pc its just them on mine. But on my account it says for like 5 games "from the library of *this account*" and i dont know if they would be able to see that or not on their account if were gamesharing like this.

I should of just said my main thats kind of confusing but yeah. Basically the games that say Borrow, but theres some free ones too that say I can play them on the other account. It doesnt say I own them or anything though. I would like to test it by making another and gamesharing with that to see by completely logging out of this one but idk if that would work like that or if i would need two different computers or smth

Family share only gives access to the games.
But on same pc, they might see installed games of yours, kind of "in their library".
Like installed games appear for you
