Absence of evidence is not evidence of absence.
FBI charging documents do make references to the telecommunications of the OK defendants, where they are trying to trap and gas congress people under the capitol.

Neither the FBI nor Capitol Police has made claim that any lethal gas was present, period. Not in possession of "Oath Keepers" or otherwise. Not in "underground tunnels" or anywhere else.
No reputable news agency seems to be claiming thus, either.
So, the burden is on the claimant to show that this isn't pure narrative fantasy.
