Angular 19 gives error TypeError: menu._startAnimation is not a function

[timothyBrake]

When upgrading to Angular 19 this module is broken.

There is an issue when the bdcwalkthrough popup should display but it does not and get the following error

TypeError: menu._startAnimation is not a function at BdcWalkTriggerDirective.openMenu (bdc-walkthrough.mjs:712:12)

When will angular 19 be supported?

Greets,

Here's a temporary fix using patch-package, if you want to use it.

If you do not know how to use patch package, Create a folder called patches, and a file inside this folder, call it: bdc-walkthrough+1.2.3.patch and place the contents of the upper code in the file.
Add this line in package.json in the scripts block: "postinstall": "npx patch-package".
Then run npm i and you are all set.

Migrated to Angular 19. Here's the pull request #35

@EliasNajem I have included your remarks.
There was one more additional issue with filter(event => event.toState === 'void') and changed it to filter(event => event === 'void'. A quick review would be great.

Pull request was merged into master. Now the creator needs to publish that to npm for people to easily use the Angular 18 or 19 build. Users can always checkout the branch and manually build it and then add the final build to their project.
