Hi @cfew
Welcome to the community!
First, we need to know what you are trying to do, because there are two different types of Power Automate. Your screenshot looks like Power Automate Desktop, this is an app you can install on your client to automate tasks using Robotic Process Automation, these flows are called "Desktop Flows", read more here: Power Automate - Desktop flows | Microsoft Learn. Then there is the web browser version, which is used in most cases and also explained within the blog post you referenced to. These flows are called "Cloud flows", read more here: Power Automate - Cloud flows | Microsoft Learn
Depending on the task you want to achieve, you need to choose between these two. In most cases you can use cloud flow as most systems have an API (Application Programming Interface), e.g. SharePoint, OneDrive, MS Teams, MS Forms and over 600 other third party connectors.
You can access the Power Automate cloud flows using this URL: https://make.powerautomate.com
Select "My Flows" or "Create":

Then you can start with a template or build your own flow. This design changed over time, the blog post you are referencing to is a bit older and doesn't look the same anymore.

Depending on what you want to automate, there might be already a template you can use, otherwise you need to create your own. Also you can see "more ways to automate" with "Desktop flow", we are not using this now.
If you select "build your own", you need to select a trigger and an action to get started:

There you already see "Scheduled" and you can configure it within the screen:

next you can select an action what you want to do:

You can also skip this wizard to just get started with a blank flow. In this case I selected to send a mail:

Afterwards you can go on and build your flow.
Happy automating! If you have any more questions, please don't hesitate to ask. If you have a new question, you should post a new thread within this community as it is more likely to be seen. Afterwards just reply on the same thread, until your question is answered. It also helps to search around within this forum as a lot of questions you might have are already answered.
Does this help you? Otherwise please give me some more information.
Best regards
Marvin
