As a risk manager, you can edit the risk assigned to you, accept the risk and look for the next steps toward resolution. If the status is chosen as Ignore, you can simply provide the reason and close the risk.

Once accepted, you can further edit the risk details such as the impact, likelihood, etc., and submit the form for further approval by choosing the appropriate approver user.
Once approved, under actions choose to Publish to Response Owner to make it available for the Response Owner who can be from the Supplying Organization or the Buyer Organization.
Now click on the Respond / Close action to establish communication with the supplier or the buyer user to work towards the issue resolution. The messages and the attachments from the supplier are visible in the messaging section. Communication between the response owner and the Risk Manager toward resolution is captured in the messaging section.
Once resolved or the risk manager has arrived at the solution, you can close the issue by clicking on the Close button. Now, this risk is removed from the active risks and is now available under the closed risks as shown. Use the toggle button to view closed Risks.
