What is the "Command Channel" device attribute for?

Hello everyone,

I'm trying to solve a specific UI problem. My main goal is to hide the "Send SMS" checkbox from the "Send Command" dialog, so that my non-admin users cannot see or use it.

(Here I will attach a screenshot of the "Send SMS" checkbox)

While investigating this, I found a selectable device attribute called "Canal de comandos" (which translates to "Command Channel"). I thought this might be related.

As you can see, this is not a key-value attribute I can type (like command.channel = sms). It's an item I must select from a list. I was hoping I could use this to control the "Send SMS" checkbox visibility, but I don't understand what it does.

So, I have two questions:

What is the purpose of this specific, selectable "Command Channel" attribute? What does it do?

Is there any way to hide the "Send SMS" checkbox from the "Send Command" dialog for certain users?

Thank you for your help.

This is only relevant if you need to use an API to send commands to the device, like Traccar Client.

No, it is controlled globally.
