Query JSON file in Presto in S3

I have a file in S3, and Presto running on EMR. I see I can use Json_extract to read the json.

I am running the following query, however, I keep seeing null instead of the correct value.

select json_extract('s3a://random-s3-bucket/analytics/20210221/myjsonfile.json', '$.dateAvailability')

I see this output

Not sure if my syntax is wrong? Thoughts?
