Specialist in wordpress (customization of the LearnPress plugin)

Hello, I need to do a customization on the LearnPress plugin, more precisely on the administrative page where we created the course (/[login to view URL]). This customization involves improving the user experience and adding functionality. The idea is to be an add-on to Learnpress or some other form that can be installed or uninstalled in case of server migrations, etc. For ease of understanding, I have separated this administrative page into several parts of the attached "Parts" file. In relation to the user experience, the creation of the course will be done through "Step by step" in the style of the "Step by step" annex. There will be 5 steps: Step 01: (new functionality - Teaching Plan) In this step, the user can download a word template file (We will send this file to you) and be able to fill in and upload a new file. You can move on to the next step as soon as you submit your education plan. Step 02: Curriculum This part already exists in the system. Step 03: Page in course This part already exists in the system. Step 04: General Settings This part already exists in the system. Step 05: Extras This step should only be viewed by Administrators. In it comes SEO YOAST widget, side widgets and side widgets. Obs: Each part I wish I had a description with a link to an explanatory video. The main side widget should be visible in all steps.
