How to correctly save a screenshot in a custom path?

Hello Unity-Community. I have a problem with my function, which should save a screenshot to a desired path:

     public void TakeScreenshot()
     {
         string folderPath = "Screenshots/";
 
         if (!System.IO.Directory.Exists(folderPath))
             System.IO.Directory.CreateDirectory(folderPath);
 
         var screenshotName = 
                                 "Screenshot_" + 
                                 System.DateTime.Now.ToString("dd-MM-yyyy-HH-mm-ss") + 
                                 ".png";
         ScreenCapture.CaptureScreenshot(System.IO.Path.Combine(folderPath, screenshotName));
         Debug.Log(folderPath + screenshotName);
     }

Although it perfectly works fine when using inside the Editor, it doesn't work when I export my project. The Screenshots folder is going to be created at the desired place, but the screenshots won't be saved. If I take the folderPath out of the Screen Capture Process, the screenshot will be created but inside of the "Data" Folder. What can I do?
