What is the top impression?

In the upper right corner of the IoT platform, after clicking the space logo, a space list will appear. In order to show the effect, the number of displayed spaces is limited here, that is, no more than 10 at most. After more than 10, other spaces need to click "more space" to view. The "top display" is to allow customers to actively set whether the space should be displayed in the list in the upper right corner of the homepage; when the upper right corner of the homepage is less than 10, the newly added space will be automatically displayed on the homepage.
