Android CaptureScreenshot not working

Been trying to get the Application.CaptureScreenshot(), on Android, for the last few days, and I can not get it to work.

I have a button set up, already made in the Canvas, with a method attached to the OnClick() events in the editor.

public void ClickScreenshot()
    {
        snapshotStatus = true;

    }

Then an IF statement, in the LateUpdate() method will recognize the boolean change:

void LateUpdate()
    {
        if (snapshotStatus)
        {
            StartCoroutine(CaptureScreen());
            snapshotStatus = false;
        }
    }

Which will go to this IEnumerator method to check if the file exists:

private IEnumerator CaptureScreen()
    {
        string screenshot = System.DateTime.Now.ToString("yyyyMMddHHmmss") + ".png";
        string filePath = System.IO.Path.Combine(Application.persistentDataPath, screenshot);
        Debug.Log(screenshot);
        Debug.Log(Application.persistentDataPath);
        

        // Wait for screen rendering to complete
        Application.CaptureScreenshot(screenshot);
        while (!File.Exists(filePath))
        {
            Debug.Log("Sanky: File exist at location" + filePath);
            yield return 0;
        }
    }

This was from looking at other questions from this site, and I still can not get any screenshots to be made. I do not get any com.projectname.app folder made with any screenshots in the file folder, or anything. Tried using Write Access Internal and External (though this device does not have a SD Card slot).

I originally had just the Application.CaptureScreenshot() in the ClickScreenshot() method, but I am at this point pulling straws for anything. Any suggestions?

By the way, when testing on the PC, the original method above works just fine.

Turns out the screenshots are inside a directory that can not be accessed w/o using a file manager.
