Question: does a mp object store anything related to vcov?

Description
After running model_parameters I am unable to find any information in the saved object about whether or not robust standard errors were calculated and the method used to calculate them. I am confused, because taking the code from this page:
https://easystats.github.io/parameters/articles/model_parameters_robust.html
data(cars)
model <- lm(dist ~ speed, data = cars)
mp <- model_parameters(model, vcov = "HC3")
str(mp)
attributes(mp)["robust_vcov"]
# $robust_vcov
# [1] FALSE
I saw the robust_vcov attribute, but it has a FALSE value even though (vcov = "HC3").
Is this expected? I'm trying to learn how things work, and I was brought to this state by trying to figure out what bootstrap method is used for "BS" but ran into this potential issue or confusion on my part. Thanks.
