What relationship does ambergris have with sea glass?

I grew up in Seattle. In my youth (1920s-30s) the search for ambergris reached an insane intensity. It was thought that ambergris was the vomit of whales and that it was used in the manufacture of perfumes, hence scarce and very valuable.

What is the connection between sea glass and ambergris?

Both sea glass and ambergris are found in proximity, the search for one could result in the finding of the other.

I look forward to your comments.

Sincerely, Robert
