Can we make the Email field mandatory when an Agent adds a candidate?

Summary:

We have a requirement to have the Email field mandatory when the agents are adding candidates.

Currently, the add candidate page is in responsive and might change to Redwood very soon, so have not explored the page composer customization options.

Content (please ensure you mask any confidential information):

The candidates are not receiving the notifications as the agents have not added their email during the initial application.

Version (include the version you are using, if applicable):

24B
