Instagram uses the igshid URL tracking parameter for shared post/reels/etc links. Everytime a user shares a post to an external app, Instagram makes an additional server request generating the igshid parameter. So a canonical post URL say https://www.instagram.com/p/foo_bar becomes https://www.instagram.com/p/foo_bar?igshid=qux.
This also takes some time making a lag and also, if I'm not mistaken, increases the number of shares for the particular post.
(N.B. The list of Instagram URL tracking parameters I'm aware of, but not necessarily generated on sharing posts, includes 'igshid', 'ig_rid', 'e', 'g', 'igsh', /^saved[-_]by$/.)
