Problem in Docking with HADDOCK

I am trying to dock Thymoquinone to spike protein(6vxx) through HADDOCK online server. But it's showing me:

Error in PDB file.
Issue when parsing the PDB file at line 1.
Your PDB contains an unknown residue UNK using ATOM record

Basically, I downloaded the mol file of the Thymoquinone structure and converted it into PDB by using Chimera. But I don't know how I replace the UNK tag with something else?
