Whatever happened to the 2 140+ speed bowlers from the U19 days

Kamlesh Nagarkoti & Shivam Mavi both played together in the U19 world cup and were positioned as the next 2 super-fast bowlers of India, since they were clocking 140 or more regularly.

Where are they? If i remember correctly they were even featured in one of documentaries by Hotstar.

Wonder what happed to them, I think they play the IPL but no mention about playing in the India - Test, ODI or T20 team.
