Help for Author Box

First of all, greetings to the generatepress family.

I have a problem. In fact, before purchasing generatepress, I had reviewed sites using this theme. I saw that they were very fast and I bought it. Most of these sites I reviewed had an author box. I thought there was an "open author box" option in the settings, but after purchasing, I saw that there was no such option. Since my coding knowledge is not enough, I tried to create an author box according to your video below, but despite trying many times, I failed every time.

Now I have a request from the generatepress family. I know it's been a lot of work but I would appreciate it if you would take the time to create a simple author box like in your video.

I love you very much and I look forward to your help.
