Dorico for Ipad for simple basic bass guitar notation

I am a senior, and a learner bass player. I want to use Dorico for Ipad to do my own notation for my bass only. My goal is to transpose to keys my friends play.
Are there any tutorials for the simplest use of this software! I can’t seem to bring up the qwerty keyboard, I can’t even seem to cut and paste. These simple tasks should be clear but all videos I’ve looked at are far too complicated for the simple tasks I’m attempting. I’m looking for the most basic approach for me to be able to accomplish this notation.
Any tips will be helpful.

Welcome, hopefully you will get a number of replies to help you Donna.
Did you see this YouTube video, or have you searched for any at YouTube? (search words, Dorico iPad)?
