Calculate AIC with not normal distributed items

Hi everyone,
I'm dealing with not normal distributed items so I'm testing my model using USLM estimator like this:

fit <- cfa(model = my_model, data = my_data, meanstructure = TRUE, = T, estimator= "ULSM")

sum_fit <- summary(fit, standardized = T, rsquare = T, fit.measure = T)

Unfortunately summmary function doesn't give me back AIC values by default. Browsing some site I found the function AIC() but I don't think I'm using it in the right way at all.

Can someone kindly indicate me the correct way to calculate the AIC in my situation?
Thank you so much

              speed   =~ x7 + x8 + x9 '

fit <- cfa(HS.model, data = HolzingerSwineford1939)
#> [1] 7517.49

Hi, thank you for your answers. I did try that but I get this error: "lavaan WARNING: logLik only available if estimator is ML[1] NA". My estimator is unweighted least square and not maximum likehood.
Thank you again
