@SaraVanNingen1 Thank you for posting your question.
This appears to be a permission issue. Creator permission at minimum is required to use analysis functions. Creators can create and edit content such as maps and apps, perform spatial analysis using the analysis tools in ArcGIS Online, collect data, and collaborate and share content for use in apps. The organization administrator can assign and change privileges that are necessary.
See the User types for more information.
Apologies the resources on this were a bit hard to find. Please let me know if this resolves the issue.
