How to use "Material 3 Design Kit" or any other library like this?

How to edit my post? I don’t get it…

Here is a screenshot to show what I mean.

Hey welcome and go read some manuals about team libraries. Gl hf

I’m not on a team, I’m on a free account and I try to learn some basic stuff about Figma. Can you tell me please how I can do it?

In this case your option is to grab a file a do stuff you want in it. Check assets panel for available components, it should not be a brainer to get those instances and make something

I can open that file and can copy-paste things from it. However, when I paste its components into my file, they stop being configurable.

For example, if I paste an icon button, it gets pasted with its default icon and I cannot change the icon: “instance swap” just doesn’t see the icons from the original file.

Now that I copy those icons via copy-paste, they don’t get visible to the “instance swap” tool, because they stop being components. Checkout the screenshots.

(I will send another screenshot in the follow-up reply due to some odd rules of this forum.)

Hence my question - how to get library contents properly. You said libraries is the right tool, but as I’m on a free account, I guess libraries are not available so my problem cannot be solved.
