[Copilot]

Docs advertise short options -i/-n for --roleId/--roleName (consistent with engage-role-member-list), but the command schema doesn't define these aliases. Add .alias('i') and .alias('n') (or update docs to remove the short options) so the documented CLI usage works.

Suggested change

	roleId: z.uuid().optional(),
	roleName: z.string().optional(),
	roleId: z.uuid().alias('i').optional(),
	roleName: z.string().alias('n').optional(),

[Copilot]

The warning text has a grammatical error and is inconsistent with the existing engage role member docs. Consider changing "once the API reached general availability" to "once the API reaches general availability".

Suggested change

	This command is based on a Microsoft Graph API that is currently in preview and is subject to change once the API reached general availability.
