Ability to record audio and attach it to form

I would like for my users to also be able to record audio and attacht it online to the form, how would I be able to do that? I wrote to the webdorado staff and they said they are not able to make custom dev right now, but maybe someone could point me in the right direction on where to start?

I found this tutorial online:

https://nusofthq.com/blog/recording-mp3-using-only-html5-and-javascript-recordmp3-js/

Would something like that work? What changes overall should I do to the code of the plugin?

Thanks!
