Missing APFS item when formatting a flash drive on Mac os Mojave?

Question

macOS

I tried to format the flash drive with APFS, but the system offers Mac OS Extended. There is also no choice of formatting with a password (data encryption).
At the same time, the built-in hard drive under APFS is formatted freely
Maybe someone knows what's wrong and what to do?

Answer 1

So a flash drive with MBR markup Needs
to be converted to GPT
