No.
You can create objects in Microflows, but not entities.
If you need to programatically create an entity, you would need to look at using the Mendix JavaScript SDK.

Hope this helps
Hello Robert,
I imagined that there was no possibility from microflow. But I think what you shared can work.
Thank you so much.
Best, Álvaro.
