Setting Default Date

Hello,   I have a StartDate property. I want to set the 15th of that month as the default value for StartDate. For example, if you are in October 2023, the date should be 15/10/2023 by default, and if you are in December 2025, the date should be 15/12/2025 by default. Then I will set it to the date I want. I know I have to use microflow. How can I do it?
