How to prevent the download icon with pdf loaded in window


#1
let winp = new BrowserWindow({
	width: 1200,
	height: 900,
	webPreferences: { plugins: true }
})
let f = `file://${__dirname}/renderer/pdfs/${isbn}/chz.pdf`

// console.log(“f=” + f)
winp.loadURL(f)

when the pdf loads there is an icon which allows a download, how do I disable this?
