Is it possible to monitor a green dot Instagram account?

I’m worried about my teenager’s online activities and I recently found out they’re using a green dot Instagram account, I’m not sure what that means or if it’s something I should be concerned about, can someone help me understand how to keep an eye on their activity?

The green dot just means they’re currently active on Instagram, it’s a standard feature. To actually see their activity, you’ll need a monitoring tool. I use Parentaler to keep tabs on messages and posts, which gives you the full picture beyond just their online status.
