Firstly, it's important to note that as of June 3rd, Instagram only allows Instagram Direct Messages for Instagram Business accounts with 10,000-100,000 followers.
Instagram intends to open up access to accounts with <10k followers and >100k followers later this year. You can learn more about their proposed rollout process here.
