[Simulation question]: How to Correctly Add Oxygen Reactions in TOPASChemistry_Extended?

[Edgarchen666]

Simulation question

Dear TOPAS Community/Support Team,
I am working with the IRTCummulative example and attempting to add oxygen-related reactions using the TOPASChemistry_Extended module. Despite multiple attempts, the configurations seem to have no effect. Could anyone advise on the correct approach?
Problem Details:

1. Direct Oxygen Concentration Declaration:
   Tried setting d:Ch/Oxygen/Concentration = 0.25e-3 M, but no changes observed.
2. Background Reaction with Oxygen:
   Added the following for the SolvatedElectron/Oxygen reaction:
   sv:Ch/TOPASChemistry/Reaction/SolvatedElectron/Oxygen/Products = 1 "SuperoxideAnion"
   d:Ch/TOPASChemistry/Reaction/SolvatedElectron/Oxygen/ReactionRate = 1.9e10 /M/s
   i:Ch/TOPASChemistry/Reaction/SolvatedElectron/Oxygen/ReactionType = 5
   d:Ch/TOPASChemistry/Reaction/SolvatedElectron/Oxygen/Concentration = 25e-6 M
   s:Ch/TOPASChemistry/Reaction/SolvatedElectron/Oxygen/ScavengingModel = "ExponentialSingleFactor"
   b:Ch/TOPASChemistry/Reaction/SolvatedElectron/Oxygen/CompatibleWithStepByStep = "True"

However, the simulation behavior of oxygen-related reactions remains unchanged.
Any insights or configuration snippets would be greatly appreciated!
Thank you for your support.
