There is no such option in our app. The only way to have two accounts in our app is to be logged in on different devices. But please, make sure that you do not connect the same personal accounts on both devices as in this case you'll connect to the same account. You can read more in this article.
In order to have a different account, you need to connect personal accounts that are not connected to your account on the other device.
If you have any difficulties, let us know via the feedback form.
