 /**
- * This function filters an array based on a property key and the value to use for filter.
+ * Filters an array of objects by checking if a specified nested value exists within any object.
+ * The search is case-insensitive and checks all nested properties by converting the object to a JSON string.
  *
- * @description
- *   The function iterates over each element in the array.
- *   If the element's value for the specified key matches the search value (it's included, case-insensitive), it is added to the new array.
- *
- * @param {array} arr - The array to filter.
- * @param {string} key - The property key to match against.
- * @param {string} value - The value to search for in the array elements.
- * @returns {array} A new array containing only the elements that match the specified value.
+ * @param {Array<Object>} array - The array of objects to filter.
+ * @param {string} nestedValue - The value to search for within the objects.
+ * @returns {Array<Object>} - A new array containing objects where the nested value is found.
