Debugin plugin when usin grafana-toolkit build

Hello all,
I’m using grafana-toolkit to build custom panel. I wanted to debug the panel using either vscode or chrome, BUT the build is minify the module… thus this is not usable at all.
How i can change this and let the module in clear.
something to do with some config file in node_modules/grafana/toolkit/src/config/ ???
Where can i found extended doc about toolkit ??

thanks

I am having the same problem. I am using the dev script to build but it is still minified for some reason.
