WORKDAY function is not available in Power-Fx

[m365solutioninsights]

In Excel, we have WORKDAY function which returns a number that represents a date that is the indicated number of working days before or after a date (the starting date). Working days exclude weekends and any dates identified as holidays. Use WORKDAY to exclude weekends or holidays when you calculate invoice due dates, expected delivery times, or the number of days of work performed.

This function is not currently on our roadmap, but it is nice to have. Feel free to contribute to the project.
