Cheking for outliers after fitting a glmmTMB

Dear all,

I am trying to check the assumptions after fitting a glmm with the glmmTMB
package.

However, I don't know how to get the Residuals vs Leverage plot and Cook's
distance. Neither the "leveragePlot(model)" nor "leverage.plot(model)"
functions do work with an object of class glmmTMB. Can anyone give some
advice of how can I get it?

Thank you so much,

Irene
