[johanna-skylight]

Area or Component

Settings Page -> Manage Organization Tab

Quick Summary

The form to update the organization information is not set with a form tag and the organization name field does not display inline errors (just the toaster)

How to Replicate

Try to submit an empty organization name and verify no inline error displays.
Inspect the DOM and verify the form is currently using a div as a wrapper.

Accessibility Violation

The required field is not identified by any of the following means: its label or form-level instructions or an error message. https://docs.deque.com/issue-help/1.0.0/en/form-error-required-unclear

Action Requested

Swap the div wrapper with a form tag.
Add inline error to the organization name input field.

As a stretch migrate this form to use react-hook-forms
