Hi @Juanique Jooste ,
If you go to your App Registration > API Permissions > + Add a permission, you should be able to see "APIs my organization uses."
If you are not able to see that option in the tab, I would recommend trying with a different browser and sharing the screenshot of what you see.
As a workaround too, you can add the permissions directly in the app registration manifest.
Let me know if this helps and if you still run into these issues after swapping the browsers.
If the information helped you, please Accept the answer. This will help us and improve searchability for others in the community who may be researching similar questions.
