Connect my paid Unsplash+ account

Hi,

I have a paid Unsplash+ account. I created an Unsplash App. It has an Access Key and a Secret Key. In Instant Images, there is only one field for the Unsplash API Key. What do I add here? Which Key do I add? Or is there more to it?

I must ensure the images I added are connected to my Unsplash+.

Thanks!
