Block IG from crawling/spidering website in .htaccess

Anybody have a code for .htaccess and robots.txt to block the Instagram crawl spider from crawling a website or redirect them?

I ask because I'm using the same root domain across my IG accounts to track click performance for individual ig profiles but they all redirect to the same url.

Best regards and stay blessed!

Figure out their IP range and or UAstring, then redirect based on those signals.
