Where to find these symbols/letters on Japanese keyboard (on phone or Ipad)

I pretty much just started learning Japanese and I’m starting off with hiragana + katana, but I already know a few words, I try to type them out and memorize them using the Japanese keyboard on my phone or Ipad, my keyboard is mainly used in english of course because thats my main language but I switched the settings so I can go back and forth, I’ve been trying to type out 大丈夫 for a bit but I can’t for the life of me find the letters/symbols anywhere, I’m still trying to find others too but mainly these ones, I’ve been able to find many of the other ones I need but I can’t with the letters/symbols that make up that word. On my phone I use 12 keys, I like using my Ipad more because the screen is bigger and more of the symbols are showing, I know I can hold down some for the other ones and there is this other thing that has more of them, but I still can’t find it in those either. Sorry if this is stupid but please help
