Set content dispoisition for a temp URL? Iframe

I'm trying to create a temp url where the content disposition is 'inline', so it doesn't download the file but it actually gets displayed within an iframe.

I've tried this, but it is downloading the file instead:
$url = Storage::disk('ovh')->temporaryUrl($path, now()->addMinutes(1), [
'CONTENT_DISPOSITION' => 'inline',
'CONTENT_TYPE' => 'text/html'
]);
