This is the Lightroom forum. You stand a better chance of getting help if you post in the Photoshop forum.
In any event, here are some thoughts: Do you have a CC subscription or are you using a stand alone (perpetual license) version of Photoshop?
If you do have a CC subscription, what you are looking for is "Libraries" under the Window menu (not CC Libraries). Then click on the "Learn more about Libraries" and explore your options there.
Thank you so much, Rafael! I will post to the PS forum.
