Our app does not have this option. The only way to have two accounts in our app is to sign in on different devices. But please make sure that you do not connect the same personal accounts on both devices, in this case, you will be connecting to the same account. You can read more in this article.
To have another account, you need to connect personal accounts that are not linked to your account on the other device.
If you're having trouble, let us know via the feedback form.
