[OPEN] [a11y] "i" Icon in Global Account Notification Alerts has no programmatic information

Engineers are currently investigating the issue.
Description
In the Notifications Centre, Global Account Notification alerts display an "i" icon to indicate the alert type, but it is only visual and not provided programmatically, making it difficult for users to understand its meaning.
Expected Behavior
The "i" icon should have appropriate attributes or alternative text so that its purpose is communicated to users.
Workaround
No workaround exists at this time.
Steps to Reproduce
-
Login as a User.
-
Navigate to the Account from the Global Navigation.
-
Click on Notification.
-
Navigate to the "i" for the Global Notification alerts.
Note that the icon’s purpose is not announced or programmatically described.
