Can you change username in Post.news app?

can you change your username in post news app so as I understand you can only do it when you create your account so after that if you go to your profile tap on Three Dots and edit profile then your handle is grayed out and it's no longer possible to change your username of course alternatively you can always reach out to their support uh like if you just go here to help section uh and then you can just reach out and search for the help here so that's basically yeah what it is at the moment
