What is the rule for other users to be able to challenge us? (Randomly)

Question

hello awesome people,
whenever I challenge another user and close the app for some time,
I got new challenge when I log in again.
Is there any rule/setup so other users can challenge me (when they choose random opponent) without me arranging a challenge first?

cheers

thanks for your response,
so that's mean I need to start a challenge first so the system will recognise me as active user and another user can be paired with me if they choose random opponent?
