Not related directly to this PR, but the following podman-desktop/podman-desktop#5744 would be a nice touch !

It seems that if there is some error while deleting we do not show anything to the user.
Maybe this can be done in a follow-up PR as you're just replacing the modal but, thinking at this future change, wouldn't it be better to await the showWarningMessage and have the deleteLocalModel outside the then?

@lstocchi Yes, we could also use ShowError api inside the backend and try catch the deletion. But this is not in the scope of this PR, as the current behavior is not supporting it either

So my first thought was wrong, by looking at the code we have a showErrorMessage if the delete action fails

If you could change the function "style" as commented by Jeff/Florent i'm good with it
