Need help creating a modern wiki

Just to give a breakdown. I am trying to create wiki site where visitors can submit articles via forms and it automatically takes the responses and creates a new article page on the site which visitors can browse and search. 

So far I created a form for submission of articles and a list to store the submissions. I am having trouble with the power automate flow portion. I have configured the trigger when a new item is created in the list, a compose to format the article, an action to create the site page, an update page content with article html action and an auto publish action. I'm not even sure I am creating the flow properly. I am beginner when it comes to SharePoint and power automate. Any suggestions or directions to a guide to where someone has done something like this would be appreciated.

In brief I want when users submit their article via a form to be published automatically as a page that others can view.

Thank you for your help in advance.
