Social Sharing Feature Image

Hi Team,

I am uses Rehub + ImportWP Pro for bulk post uploads. I want to auto pull/show post featured image while posting post URL to Facebook, Whatsapp, etc. I guess it will be enable using Facebook OG Image. I am trying to Add og image by ImportWP’s Yost SEO plugin settings field “Facebook Image location” by adding image url. But seems its not working.

Can you please guide me how to do it properly ? Can Upload external url as og:image ? or it should be downloaded on my hosting location ?

Thanks
