Geometric nodes fill 3D curve similar to fill edges (alt+f)

Hello, is this possible with geo nodes somehow? I found some solutions to fill closed 3d curves, but all fails when there is another closed 3d curve inside.

You can use a Fill Curve node. But that is only useful for flat curves on a X-Y plane:

There is a method to somehow make it work with 3D curves:

But this is more of a hack IMO. It will break really fast, if there are some overlapping curve segments in the X-Y plane…

Many Thanks Zebr4, that works perfectly for my case! Learning GN and trying to make sort of tile/floor generator for uneven surface and I need this to generate some of the border tiles.
