When using occbin, is it necessary to independently solve for the steady state under the OBC?

Dear Professor, I would like to inquire whether it is necessary to explicitly derive the steady state under the OBC when using occbin. For instance, when facing the ZLB problem, should one separately calculate the steady state under the ZLB or is it sufficient to directly use the original mod under the Taylor rule scenario?

The model setup in Occbin requires the model to converge back to the baseline regime. Thus, there must be only one steady state.
