how do i gameshare on ps5 without wasting hours?

Worth knowing before you set it up: only one PS5 can have console sharing switched on for your account. So turning it on at your friend's turns it off on yours. You can still play your own games on your own console, you just need to be signed in and online for it.

the step everyone misses is that it's done on your FRIEND's console, not yours. they log into your account on their ps5, go to settings > users and accounts > other > console sharing and offline play, and turn it on. then they switch back to their own profile and your games + ps plus work for them. only one console can have it on per account, so turning it on there turns it off on yours. you can still play everything on your own console while you're signed in.
