To prevent false joining in voice chat

As a mobile phone user,I sometimes join voice chat falsely when I am suppoed to open keyboard,or push home botton.This situation is so annoying not only to me,but also voice chatting members.

In order to prevent this,I suggest Discord to set botton to ask users about confirmation of joinning.(So,it's enough to do what image ② shows,but it would be less annoying to us to delete the "join voice chat" botton below)

Thank you for redading.Also,I'm sorry for these poor English.I'm not a native speaker.
