How to stop wavesurfer microphone / `this.stop.stream` is not a function

问题

I'm running this wavesurfer microphone instance and i'm running into a problem called this.stop.stream is not a function whenever i'm trying to stop the microphone after starting it.

This mic does not record anything - it's just visualizing. But in chrome the mic just stays open until reload. Which is not fun for users. And m.

I have found why that happens here => https://wavesurfer-js.org/api/file/src/plugin/microphone.js.html#lineNumber199

all the methods that are called after starting the mic are with "this".

I'm not advanced enough to find out how i could possibly stop that microphone.

Can someone help me please?

Thanks in advance
