Take prevention for mobile video calling!

I use Discord on my phone in my daily life. I send a lot of messages to my friends, so I actively use Discord. Since the screen of the phones is small, we already have a limited space for touching. When starting a video call on mobile, maybe should ask us twice. Clicking by mistake, starts a video call directly. This reveals us and our personal life. Please solve this, I want to use Discord more easily and peaceful!
