help in DFC(DF CONNECTED as other say)

Hey everyone, Buildy here, i am needing help in DFC(DF CONNECTED), i am playing with my brother, but i don´t know how to send a friend request. And yes, it is possible to have friends in that game, by pressing Tab, you will open the player list, and it will appear a friend count. So, for anyone who can help me, send me an e-mail in my alt account: [sketchysarereal@gmail.com] or awnser me here if you want. Thank you for reading(if you didn´t you´re so lazy).
