# initialize using environment variables from elasticapm.contrib.flask import ElasticAPM
app = Flask(__name__)

# configure to use ELASTIC_APM in your application's settings from elasticapm.contrib.flask import ElasticAPM
app.config['ELASTIC_APM'] = {
    # allowed app_name chars: a-z, A-Z, 0-9, -, _, and space from elasticapm.contrib.flask
    'APP_NAME': 'flask-apm-client',
    'DEBUG': True,

apm = ElasticAPM(app, logging=True)

@app.route('/foo')
def foo_route():
    return foo()

@elasticapm.capture_span()
def foo():
    return "foo"

if __name__ == '__main__':
    app.run()

Is it possible to use the decorator @elasticapm.capture_span() within another class/module after ElasticAPM has been initialized? I have quickly given it a try and it doesn't seem like it, but perhaps you'd be able to tell me otherwise.
