Question Help with custom post

[velvet]

HI there!

I am trying to build a website with listed posts (I am guessing custom post pages). On homepage, there will be list of courses in a grid (image "section 3 course grid"). The visitors will be able to post a course by filling in the form ("section 1 post course") that will then appear displayed as in image "section 2 course overview". This course overview will be accessible when you click on a certain course in the course grid on the homepage (as shown in the "section 3 course grid"). The trick is that I don't want them to have access to wordpress dashboard, they will be able to fill in this form and create the post on the website itself.

I am new to Elementor and I am not a developer, so I am trying to find a way to do this, or to know which tools I should explore to achieve this, especially how to connect the form and the info inserted into its fields and the post content itself. Any help or suggestions are much appreciated!

Thanks!
