Share Image Android / iOS

Hey. I have a "Share" button script that sends a screenshot of the screen. How can I send any other image?

I tried to work with the folders StreamingAssets and Resource. But for some reason, it did not work.

The task is to replace screenShotPath with a link to own image * .png.

     public static string content;
     public string ScreenshotName = "screenshot.png";
 
     public void Sharing (){
 
         Application.CaptureScreenshot(ScreenshotName);
         ShareScreenshotWithText (content);
 
     }
 
     public void ShareScreenshotWithText(string text)
     {
         text = content;
 
         string screenShotPath = Application.persistentDataPath + "/" + ScreenshotName;
 
         Share(text,screenShotPath,"");
     }
