Ability to only show changelog entries in the widget with a certain category

I would like to be able to use the changelog widget with certain changelog posts filtered out. The ideal solution to this would be to be able to choose categories to include in the initialize script such as:

```Featurebase("initialize_changelog_widget", {
organization: "vero",
placement: "right",
theme: "light",
fullscreenPopup: true,
categories: "category_1, category_2"
})```
