TLDR; documentPicker.directoryURL = <#your folder directory#>

You need to use a UIViewControllerRepresentable and a Coordinator Class. The Class can be nested inside your Struct. The present it where required with a .sheet()

import Foundation
import SwiftUI

struct DocumentPicker : UIViewControllerRepresentable {
    
    func makeCoordinator() -> Coordinator {
        Coordinator()
    }
    
  class Coordinator : NSObject, UIDocumentPickerDelegate {
        
        func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
            
            //the function gives an array of urls for the selected file.
            //chances are only going to be one
            guard let url = urls.first else { return }
            
            /*
             when trying to access resources outside our apps sandbox its important
             to call startAccessingSecurityScopedResource(). Then stopAccessingSecurityScopedResource().
             Once we have finished.
             */
            let secureAccess = url.startAccessingSecurityScopedResource()
            
            //handle your file however needed for your app
            //   .... your action ......
            if secureAccess {  url.stopAccessingSecurityScopedResource() }
        }
    }
    
    //These are required to me implemented. Though one we just can leave empty
    func makeUIViewController(context: Context) -> UIDocumentPickerViewController {
        let documentPicker =  UIDocumentPickerViewController(forOpeningContentTypes: [<#UTTypes#>], asCopy: true)
            documentPicker.directoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first! //<-- This opens Files App to your Apps Documents Folder
            documentPicker.delegate = context.coordinator
     return documentPicker
    }
    
    func updateUIViewController(_ uiViewController: UIDocumentPickerViewController, context: Context) {
        //can be left empty but the function must exists
    }
}

You can open Files app in specific folder using shareddocuments: URL scheme and providing file path.

Example:

func getDocumentsDirectory() -> URL { // returns your application folder
    let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
    let documentsDirectory = paths[0]
    return documentsDirectory
}

let path = getDocumentsDirectory().absoluteString.replacingOccurrences(of: "file://", with: "shareddocuments://")
let url = URL(string: path)!

UIApplication.shared.open(url)

P.S:
