Trying to Flatten My Json using CosmosDB Spark connector - Azure Databricks

Question

Hi,

Using the below cosmos DB query it is possible to achieve the expected output, but how can I do the same with spark SQL in Databricks.

   COSMOSDB QUERY : select c.ReportId,c.ReportName,i.price,p as provider from c join i in in_network  join p in i.provider

Source JSON

{
    "ReportId":"F0001",
    "ReportName":"ALYX_HLT",
    "in_network":[
     {"provider":[1,2,3,4],"price":10},
     {"provider":[1004],"price":100.2},
     {"provider":[39,52],"price":3}
    ]
}

Expected Output

[
 { "ReportId":"F0001","ReportName":"ALYX_HLT","provider":100,"price":10},
 { "ReportId":"F0001","ReportName":"ALYX_HLT","provider":200,"price":10},
 { "ReportId":"F0001","ReportName":"ALYX_HLT","provider":300,"price":1.3},
 { "ReportId":"F0001","ReportName":"ALYX_HLT","provider":400,"price":23.1},
 { "ReportId":"F0001","ReportName":"ALYX_HLT","provider":500,"price":23.1}
]
