Help: concatenate, skip blanks, add line break

Hello,

I am looking for help on writing a formula that will concatenate cells, ignore blanks, and add line breaks on those that do not have blanks.

The data: I have a list of people and they have different meetings they need to attend. I want to concatenate all their meetings into one cell, with line breaks, but ignore the blank cells.

Final result wanted in one cell:
Meeting 1
Meeting 3
