Debuging jsfl files for an Animate 2019 extension

Is there any tool to debug .jsfl files in which you can set breakpoints, inspect variables, etc ..., something similar to the Extendscript Toolkit or the vscode debugger?.

I come from extendscript and I'm new to jsfl, so what I'm doing is launching my jsfl script through a button on a CEP extension. The only way I have found to know what is happening is an.trace, but it is a pain debug like that. I've searched the internet but I could not find anything about properly debug on Animate.
