Additional notes on interactive debugging - especially when run under wsgi/apache

Folks,

Have looked around for additional notes on enacting and using interactive Dash debugging but have found only the initial announcements, from which I’ve tried to get the debugger working but regardless of error(s) have never seen it display.

Does anyone have any notes on getting it working for them? Especially when run from wsgi/apache?

I think it would be especially helpful to be able to invoke the debugger interface at will, simply a call to the interface, perhaps during a layout update, and turn it off as well, of course,

Thanks,
KWL
