Custom new button in data grid

I set the "new" button to call Microflow. When I click the button it should open a form for saving the attributes, but instead it asks me to choose from a table, why? Why doesn't it open the form?

In the microflow you have attached to the button you have an input parameter set.

This will require the button on the grid to pass a selected object. Remove the input parameter from you microflow and make sure to create the new object and open the page from the microflow.
