Description 😯

When giving permissions to a group (probably on workflowitem level), the pop-up remains frozen after clicking "Confirm", the only way to exit the pop-up is to click on "Cancel", as seen in the screenshot below:

However, after clicking cancel and checking, it was noticed that the permission granting actually worked.
So the problem probably is that the "Confirm" button doesn't trigger a confirmation message and doesn't close the pop-up.

How to reproduce 🕹

To reproduce the bug you need to force the frontend to return an error, for example by going to frontend/src/sagas.js in the function assignProjectSaga and adding throw new Error(); in the tryblock - don't forget to remove this once the fix is done!
