My question is actually being answered already here: Blender 3.0.0 - How to use a vertex group in geometry nodes?

... however the solution does not work for me.

If I am connecting the selection field of a "Separate Geometry" node to the "Group Input" node, it generates a new entry field in the modifier view. However the values permitted/accepted there are 0 and 1. Nothing else. I cannot specify a vertex group name there. None of the available input types (String, Boolean, Collection and many more) will also allow any such entry.

So: How can a specify a vertex group as an input/selection for a "Separate Geometry" node?

Thanks in advance

In the Modifier, you need to click on the icon after Selection and then left click on the field. This will bring up a menu that will allow you to select the vertex group. Here's an example from one of my setups. The menu will show different values for you, of course:
