How to output a spyrmsd.molecule.Molecule object

[Feya]

If we want to load a Molecule, we may use the Molecule.from_rdkit(mol).
But If we want to output a spyrmsd.molecule.Molecule object as a .sdf for example, how shoule I do this?
I've tried to use RDkit SDWriter

writer = SDWriter("outputpath.sdf")
writer.write(mol)

it doesn't work becuase the SDWriter is supposed to apply to rdkit.Chem.rdchem.Mol object, not spyrmsd.molecule.Molecule object.

So my question is how could I output a spyrmsd.molecule.Molecule object to sdf file?
If there is no direct method, maybe we could transfer the spyrmsd.molecule.Molecule object to a rdkit.Chem.rdchem.Mol object first (without changing any of the conformer's coordinates) and then output using rdkit SDWriter. How shuold I do that?

Thank you very much!

Oh I realized that the initial rdkit mol is good to use. I don't have to find a way to convert the spyrmsd.molecule.Molecule object to rdkit mol.

But I'll keep this issue open in case anyone may be interested.
