Trying to filter data in custom visual

Good evening,

I'm relatively new to Power BI and want to create a filter for my data in my custom visual so my data will be updated in every other visual/slicer on the same page. Right now I have this d3 graph with a click event on an edge which gives me an array of slection ids. These ids I am passing to the selectionManager and select them. The result is highlighted data in every other visual, but how can i create a filter out of this selection (like a filter I get from a slicer).

Code (summarized)
