The type Help Text region shows all the help text in one place (in this region).

For example, you have 10 page items on your page, and you have specified the help text for every or a few page items. Below is how you can specify the help text for page items:

Click on the page item, and in the property palette > Help section, you will find the property Help Text. Specify the help text for that item. Below is the screenshot:

When you run the page, you will see a question mark icon right-side of the page item. And when you click the help text will appear. Below is the screenshot:

Now suppose you have specified the help text for almost every item on the page. Then the Help Text Region helps to display all help text in that region.

The better way to show the help text region is by using the region display selector. Because if the help text region always displays, it will not look good.

To display it using the region display selector, follow these steps:

Create a region and set its type to region display selector. Set its position to Breadcrumb Bar and Template to blank with attributes.

Then click on the Attribute node of the display selector and turn-off the include show all property.

Now create a region and set its type to Help Text. Set its Region Display Selector property button on.

Click on your other region, which has the page items, and set its Region Display Selector property button on.

Now save the changes and run the page. You will get the output as below:
