PHPStorm does not highlight data from Vue mixins. Can be corrected?

Question

phpstorm

Just got acquainted with Vue mixins, you can very easily get rid of code duplication in components.
In the component, I do it simply mixins: [mixin](I import the mixin from a separate js file).

Everything works fine, but the IDE does not highlight the methods and state variables from the mixin file.
Am I connecting the mixins wrong or is it normal that the IDE can't highlight this?
p.s. the vue plugin is installed.
