Looking for keyboard app for Samsung Galaxy A52

After four years, I finally got myself a new phone – a Samsung Galaxy A52. I’m looking for a keyboard app that meets my requirements, and I’m hoping you can guide me to the right direction.

My requirements are:
1) I need arrow keys on the screen at all times.
2) I need to be able to have a customizable user dictionary that allows me more than one line of text. (Some apps I’ve tried, when I’ve typed a line of text and then the return key, ignore the return and will keep the text that’s supposed to be on the second line, on the first line.)

Thanks!
