You need to choose English instead. In that category you will find ABC Extended. Use the + to add it, then go to the input menu at the top right of the screen and click on the icon there and choose this one

Then you can easily make your breves via option B and then the vowel.
But you never mentioned Hebrew before. Do you want to make those two diacritics over Hebrew script letters like א? If so, let us know, as that requires something totally different.
Or are you using a Hebrew hardware keyboard to write English or some other Latin script, or making Latin letters by pressing Caps Lock on a Hebrew keyboard layout?
