How to merge an HFS+ partition into my APFS partition

merge partition apfs hfs+
  1. Choose the internal drive (Apple HDD...)
  2. Hit "Partition" in the top row
  3. Choose the freeMacPartition slice of the pie
  4. Hit the --button and then the Apply-button

The freeMacPartition has to be located downstream of (or "after") the APFS container in the partition table or merging won't work.
