Suggest how I can achieve this effect ?

info

I want to implement something similar to the example in this link, where the example demonstrates the creation of a video tag.

1. What I want to create is a span tag instead.
2. I hope to add a className of "badge-insert" and be able to place it within $getSelection.
3. The linked document example provides guidance for a video tag, but my needs are specific to the span tag and the additional class. Can anyone guide me on how to adapt the provided example to my specific requirements? Thank you!
