Explore the possibility of embedding the org-id guide link with link back to AidStream

[anjesh]

Currently when the user is taken to the org-id.guide organisation finder and from there, it takes to external link. We need to see how we can ensure that user sees that she has come from Aidstream and then her objective is to find that piece of organisation information and go back.

We need to explore iframe or other possible solution to see how this could be achieved.
