Dear,

you are correct, I tried it and it doesn't work.
i use construction a lot for other functions, but it now occurs to me that it can't be used in this case.

My mistake

The solution you suggest is indeed the correct one

Met vriendelijke groet,
Best regards,
Mit freundlichen Grüßen,

This is a somewhat strange suggestion, did you try it?
