How to request runtime permission for PDF in android 13(API level 33)?

Question

I am trying to access a PDF file from external storage, but the request for runtime permission to access the PDF file is not working on Android API level 33 (Android 13). Could you please provide a solution that works across all Android API levels?

My Code Please check this code; the permission dialog is not popping up in Android 13 (API level 33).

//all variable and function related to take image and pdf from gallery
private val REQUEST_PERMISSIONS_CODE: Int = 123
private val getContent =
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
        if (result.resultCode == Activity.RESULT_OK) {
            val data: Intent? = result.data
            if (data != null) {
                if (lType ==1){
                    uriPdf = data.data!!
                    val path = getRealPathFromURI(uriPdf)
                    binding.imgGstName.setText(path.trim().substring(path.lastIndexOf("/") + 1))
                }else if (lType ==2){
