How to access sapply output including lmer

Question

I'm trying to estimate and simulate various models. I can fit many models with sapply but somehow, I'm unable to access the output.

models <- sapply("accept.progov ~ ptot_dev+swacceptcn+(swacceptcn|coal.general)", FUN = function(X) lmer(X, data=dbq))

I got that far, that I can work with the model by further applying sapply, for example, to simulate:

sims <- sapply(X = models , FUN = function(X) sim(X, n=10))

However, now I need to extract the fixef and ranef of sims. By printing models or sims they look fairly like lmer outputs, but they are not. It seems logical that I get such an error message when trying to access fixed effects as with lmer output:

sims@fixef
Error: trying to get slot "fixef" from an object of a basic class ("list") with no slots

class(sims)
[1] "list"

Any idea on how to access the output (or convert it to be able to access it)?

Thanks

Here's the output of sims:

sims
$`accept.progov ~ ptot_dev+swacceptcn+(swacceptcn|coal.general)`
