如何循环访问多个子数组并在单个JSON中检索数据点

我正在处理Jolt变换，但我无法实现所需的输出.

Json输入-

question- how to loop through multiple sub arrays and retrieve only instance id and its respective datapoints. There are a lot of sub arrays without instanceId but we need only instance id and the content in subarray.

required output-
get the account id which is in the first line, and include it in the output array with instance id , average and timestamp.

[ { "Account_id":"297410879665"， "INSTANCE_ID":"i-06e33d65e1656d9a0"， "平均值":"34.0627"， "Timestamp":"2024-01-18 05:58:00+00:00"， "单位":"百分比" }, { "Account_id":"297410879665"， "实例id":"i-0b82b815af164734"， "平均值":"34.0627"， "Timestamp":"2024-01-18 05:58:00+00:00"， "单位":"百分比" } ]

note- 
kindly look into this and give possible jolt spec or even give any ideas on how to approach this. Please comment if you have any doubts regarding the input and output.
I will reply to your comment as soon as possible 


Thanks in advance.
