How to get members of returned data object from a filter

I have tried using the ZBarFilter, however, I am a bit stumped on how to actually use the data off this?

data:
{timestampMillis=1636564569196, codeType=CODE-128, source=f2eb56c8-be6d-4694-ae93-854d0355766e_kurento.MediaPipeline/_kurento.ZBarFilter, type=CodeFound, value=ABC-abc-1234, tags=[], timestamp=1636564569}

am I meant to convert the = into : and then do JSON.parse(modifiedFilterEvent.data)?

or do I need to parse it some other way?

Your suggestion seems reasonable.
