How to filter an array with an expression?

[JesusPrim]

Hi I'd like to filter this array

[
  {
    "Id": "JTJmZG9jdW1lbnRsaWJyYXJ5JTJmRXN0YWRvK2RlK0N1ZW50YSUyZjIwMjEwNyUyZjIwMjEwNy0xMjM0NTYucGRm",
    "Name": "202107-123456.pdf",
    "DisplayName": "202107-123456.pdf",
    "Size": 11598,
  },
  {
    "Id": "JTJmZG9jdW1lbnRsaWJyYXJ5JTJmRXN0YWRvK2RlK0N1ZW50YSUyZjIwMjEwNyUyZjIwMjEwNy0xMjM0NTcucGRm",
    "Name": "202107-123457.pdf",
    "DisplayName": "202107-123457.pdf",
    "Size": 11598
  },
  {
    "Id": "JTJmZG9jdW1lbnRsaWJyYXJ5JTJmRXN0YWRvK2RlK0N1ZW50YSUyZjIwMjEwNyUyZjIwMjEwNy0xMjM0NTgucGRm",
    "Name": "202107-123458.pdf",
    "DisplayName": "202107-123458.pdf",
    "Size": 11598
  }
]

basically I need to filter the object.Name = "202107-123456.pdf"  

but I need to filter by making splits and just validate this 123456.

to be able to get this object like this:

 {
    "Id": "JTJmZG9jdW1lbnRsaWJyYXJ5JTJmRXN0YWRvK2RlK0N1ZW50YSUyZjIwMjEwNyUyZjIwMjEwNy0xMjM0NTYucGRm",
    "Name": "202107-123456.pdf",
    "DisplayName": "202107-123456.pdf",
    "Size": 11598,
  }

I did something like this but returns Empty array.

@equals(split(split(item()?['Name'], '.')[0], '-')[1], '123456')

thanks.

Instead of splitting it you can make use of the contains action, it helps to check whether a collection has a specific item. Return true when the item is found, or return false when not found. This function is case-sensitive.

I have tried doing a test from my side and it is working as expected and I was able to get the resulting value.
