R help - Jun 2024 - emmeans (component = " response", type = "response")

I am estimating fairly simple zero-inflated negative binomial models in glmmTMB.
The models have just two factors and their interaction, a total of 4 levels.  I
was trying to use emmeans() to obtain estimates and 95% CI for these four
levels.  However, when I use emmeans() with the arguments
component="response", type ="response", I do not get
estimates that look like the negative binomial (conditional) part of the model
multiplied by 1 - zero-inflation probability.  Not sure what I am getting and
have not found documentation yet.  I can get the negative binomial part with
arguments response = "cond" , type = "response" and the
zero-inflated parts with arguments response="zi", type =
"response" and easily relate these back to parameter estimates.  How
do I get the zero-inflated mean negative binomial counts estimated in emmeans? 
I was led to believe that components="response" , type =
"response" would do that but that does not seem to be the case.

Thank you

Brian
