Yes, you can. To do so you need two different accounts with two different e-mail addresses.
We will set up access as a Company Manager for you. In most cases, an e-mail address is used for this, which several people in a specific area can use, e.g. "email@example.com".
To use the app as an employee, you need to use a different business email address, e.g. "firstname.lastname@example.org". If you don't have another business email address and you can't create a new email address, you can also use your private email address.
You can then create and invite yourself as an employee on the platform.
