I want to combine two JSON datasets in a flow

I’m trying to amalgamate two JSON data sets in a flow. I have outlined below an example of what I need to achieve.

Data set 1 (clients)

[
{
“Id”: “ABCD”,
“Department”: “C1000”,
“status”: “Active”
},
{
“Id”: “BCDE”,
“Department”: “C2000”,
“status”: “Active”
},
{
“Id”: “CDEF”,
“Department”: “C4000”,
“status”: “Active”
}
]

Data set 2 (Jobs)

[
{
“jobclient”: “BCDE”,
“jobdept”: “C6000”,
“key”: “12345”
},
{
“jobclient”: “BCDE”,
“jobdept”: “C6000”,
“key”: “14765”

},
{
“jobclient”: “ABCD”,
“jobdept”: “C6000”,
“key”: “1275”
},

{

“jobclient”: “CDEF”,
“jobdept”: “C6000”,
“key”: “2345”

},

{

“jobclient”: “BCDE”,
“jobdept”: “C6000”,
“key”: “182245”

}

]

Required output would be a ….

[

{

“Id”: “ABCD”,
“Department”: “C1000”,
“status”: “Active”,
“jobclient”: “ABCD”,
“jobdept”: “C6000”,
“key”: “1275”

},

{

“Id”: “BCDE”,
“Department”: “C2000”,
“status”: “Active”,

“jobclient”: “BCDE”,
“jobdept”: “C6000”,
“key”: “12345”

},

{

“Id”: “BCDE”,
“Department”: “C2000”,
“status”: “Active”,

“jobclient”: “BCDE”,
“jobdept”: “C6000”,
“key”: “14765”

},

{

“Id”: “BCDE”,
“Department”: “C2000”,
“status”: “Active”,

“jobclient”: “BCDE”,
“jobdept”: “C6000”,
“key”: “182245”

},

{

“Id”: “CDEF”,
“Department”: “C4000”,
“status”: “Active”,
“jobclient”: “CDEF”,
“jobdept”: “C6000”,
“key”: “2345”

}

]

The output needs to run through the client dataset and create a record for each time it finds a match in the jobs dataset.

I’m sure it will require an “Evaluate” block and use the $map function but I have no idea how to write it. Can anyone help?
