Connectable HID device

I’m running a HID device on an Artemis Thing Plug board. I can pair with the board and it works as a keyboard. What doesn’t work is that, after pairing, I can’t connect/disconnect. For example, if I look at my smart watch on my iPhone the options for it look like follows

But for my HID device it looks like so

As you can see there is no Disconnect option. That’s what I want to have for my HID device. I know that in order for the devices to pair only once they actually have to bond (pairing + saving the security information for any future connections). I think my HID code actually does bond. I’m not sure if bonding works correctly but that is a next step to solve.

My question is: how to get an option to disconnect/connect? How does my iPhone know to offer those options to the user? Not even sure how to find more information about this.
