New line / Line Break after added new image in the editor

Describe the bug
Need to move the cursor to next line after i added image in the editor. Now, the cursor is right side of image.
Tried to add " \n and br tag " like below

func insertImage(_ image: UIImage) {
        let attachment = richTextView.replaceWithImage(at: richTextView.selectedRange, sourceURL: fileURL!, placeHolderImage: image)
        attachment.size = .full
        attachment.alignment = ImageAttachment.Alignment.none
        if let attachmentRange = richTextView.textStorage.ranges(forAttachment: attachment).first {
            richTextView.setLink(fileURL!, inRange: attachmentRange)
        }
        
        richTextView.becomeFirstResponder()
//        richTextView.text = richTextView.text + "\n"
//        editorView.setHTML(editorView.getHTML()+"</p>\n<p>")
        
        let imageID = attachment.identifier
        let progress = Progress(parent: nil, userInfo: [MediaProgressKey.mediaID: imageID])
        progress.totalUnitCount = 100
    }

//        editorView.setHTML(editorView.getHTML()+"</p>\n<p>")
//        richTextView.text = richTextView.text + "\n"

Nothing worked.

Reproduce the issue using the listed steps, then trace insertImage(_:), especially richTextView.replaceWithImage(at:sourceURL:placeHolderImage:) and the subsequent selection handling. Confirm that inserting an image leaves the cursor on the following line without requiring a keyboard return, while preserving the attachment and link behavior shown.
