WARNING:param.main: pn.extension was initialized but 'jsoneditor' extension was not loaded

[MarcSkovMadsen]

When I run the quick start example https://panel-extensions.github.io/panel-reactflow/#quickstart I see

WARNING:param.main: pn.extension was initialized but 'jsoneditor' extension was not loaded. Since the application is still launching the extension was loaded automatically but we strongly recommend you load the extension explicitly with the following argument(s):

pn.extension('jsoneditor')

Please make sure the quick start example does not raise warnings.
