Only space administrators can access the space analytics
As a space administrator, you can look at the analytics of your space by accessing the Space settings by using the three little dots like shown here.
You will find a dedicated tab in your space settings. On this page, you will be able to get an overview of the contents, space activity, most active users and trending content.
The different blocks are similar to the ones for the Platform Analytics. All the explanations can be found here.
