Hi Andrei,
First of all thanks for your purchase! Don’t worry and we’ll find the solution.
PokaTheme uses the WordPress Gutenberg editor, which uses blocks. I hope you are familiar with it, and that you haven’t installed the Classic Editor plugin, right?
If this is the case, then you can add one of the PokaTheme blocks we made, by going to a new/existing page, click on the “+” icon and searching e.g. for “Poka” to see PokaTheme blocks. Then you can choose one of them e.g. “PokaTheme Carousel” and this way you can add it to your page.
Once you add it to your page, each blocks has some options e.g. for layout, texts, etc. which you can also edit.
You can have a look at our Documentation as well: https://pokatheme.com/pokatheme-documentation/
