Ability to turn off phone and video chat options

Is there anyway when you are DM someone, that you can implement in the settings to turn OFF the phone and video options that appear at the top of the screen. I cant tell you how many times i have accidently hit that on my phone and its accidently called someone that i NEVER wanted to try and call. This can be embarrasing esp if you dont know the person, you then have to explain why it happened and hope they understand it was a mistake and you are not trying to be creepy. Since you CANT delete the call chat log like you can a message, it makes it worse. Could you please at least allow us to delete the call message from the DM chat like you can all the other messages if you so choose? If that cant be done, can we have a settings option to turn off ALL calls and video chat so those buttons are greyed out if you never want to use that feature? OR lastly could you at least put up a verify you want to make this call before it calls... Like a screen before it tried to connect to confirm do you want to call this person? Any of the options would be very helpful. Either delete the call log from the chat DM, turn off the ability to make those calls from a settings menu option, or a second step verification that you really want to call said person. It would save some embarrassing moments, esp when you are talking to people you only know while gaming and not in real life... Please consider any of these options as something to be added in the future.
