Linking Instagram "business/blog" page feed

I have a block on my website footer (Brine) for my Instagram personal page feed ~ no problems adding or formatting, etc. 

However, I would like to display my Instagram "business/blog" page feed as well.  This account is linked to my personal account and I can switch back and forth between them in Instagram.

I cannot figure out how to link this secondary account in the Squarespace "ADD AN ACCOUNT" function.

Has anyone done this successfully?  I must be missing something.

Thanks, Michele
