You could retrieve the user roles of the current user. If you want to change the user roles retrieve the user rol and add this to the list of the user.

The roles that have access to a microflow from the navigation are configured on the microflow itself, not in the navigation. You can do this in two ways:

1. Open the microflow. In the properties pane (usually on the right side of the modeler), in the "Allowed roles" property, you can select the module roles that have access.
2. Open the module security for the module, on the tab "microflow access" you can select which module roles can access which microflows.
