I want to create a dash app that has access to parameters passed in address. For example, http://localhost:5050?config=bob.json
@app.callback(
dash.dependencies.Output('funnel-graph', 'figure'),
[dash.dependencies.Input('Manager', 'value')])
def update_graph(Manager):
config = ... # get config value of 'bob.json'
# Do something with config and Manager
...
