Hi team, a very basic question - I have the following event coming to Datahub-Actions. Can you tell the best way to serialize this so that I can extract information out? I will prefer json serialisation but am okay with anything else as long as it is writtable in Python

EventEnvelope(event_type='EntityChangeEvent_v1', event=EntityChangeEvent({'entityType': 'dataset', 'entityUrn': 'urn:li:dataset:(urn:li:dataPlatform:snowflake,user.l0.company_info,PROD)', 'category': 'TAG', 'operation': 'ADD', 'modifier': 'urn:li:tag:pii', 'parameters': None, 'auditStamp': AuditStampClass({'time': 1683562084007, 'actor': 'urn:li:corpuser:datahub', 'impersonator': None, 'message': None}), 'version': 0, '__parameters_json': {'tagUrn': 'urn:li:tag:pii'}}), meta={'kafka': {'topic': 'PlatformEvent_v1', 'offset': 4415, 'partition': 0}})
