Change the font of the TokenLabels

Hi, How can I increase or change the format of the tokenlabels in this graph:

graph = ResourceFunction["TokenEventGraph"][reactions, 
   startingMolecules, 1, "EventDeduplication" -> True, 
   "EventLabeling" -> "Colors", "TokenDeduplication" -> True, 
   "TokenLabeling" -> True, GraphStyle -> Automatic, 
   GraphLayout -> {"SpringElectricalEmbedding", "StepLength" -> 5}, 
   VertexSize -> Big, EdgeStyle -> {Arrowheads[Medium]}, 
   ImageSize -> {1500, 1500}, VertexLabels -> None];

You could use the documented option “TokenStyleOptions”
