Hard Time Starting a Genially Build

I'm a contractor for a local government tasked with teaching M365; I've been on this job for a few months and have a full curriculum plan designed for the major tools. I've run the first of my learning tracks (5 modules) through Teams but am now designing a self-paced version focusing on the Teams app content. However, while I have a plan for what I want the modules to include, I'm just having a brain freeze about actually building it. Here are the details:

• 6 modules total, each one a specific Teams feature focus (level one/intro topics)
• Story feature - participants act as a new hire for a company using tools to complete tasks
• Each module includes an intro, walkthrough, mini-challenge/gamified task, knowledge check, wrap-up/link to next module

While I used Genially as a teacher for high school, I've been an ID for about 5 years and have used other tools (Articulate 360/Rise, Camtasia, Vyond, LMS, Forms). I don't have much tool access at this job, so screen recording, static resources (PDF creation/PPT/images), and Genially are what I have to work with.

So, my questions are:

1. Am I on the right track? (I honestly never thought I would mind working as a team of 1 but in this instance not having people to bounce ideas off of is very limiting)

2. Genially users: how would you build this out? I am starting with interactivity of just clicking on specific parts of pictures/visuals, but any additional tips would be helpful.

3. Is there another tool I should be considering?

Thank you!
