I would like to use the asset library, but everything I add to it is only stored on the current file which is of little use. There's no intuitive way to add assets to the main library and apparently there's supposed to be an append option, but I don't see an append option.
What am I missing?
Add selected data-block(s) in Outliner to the library on current blend file
Here is the script to achieve this:
Make sure the current blend file is saved

It will open the _lib_.blend and append the selected data-block(s), mark the assets, save, and open the current blend file again.
you can save your blenderfile in folder User Library. User/Documents/Blender/Assets/ is default location. And local assed are now add to main libary.
If you want place them in catalog in main libary. you might need to reopen the file. by right clicking on the assets.
Hope this helps.
Copy the file to your Assets file in your blender file, if it doesn't exist create it, else change your file path in preferences. Then open your file which you placed in Assets, choose the object in your Outliner usually on the right right click the object and Mark as Asset it worked for me. Don't forget to save your changes and reload the file where you want to access your new added assets.
