Set Trigger on ALTER_SERVER_ROLE I've tried to add a trigger to the ALTER_SERVER_ROLE command using:
CREATE OR ALTER TRIGGER XXX
    ON ALL SERVER
    FOR ALTER_SERVER_ROLE AS

It creates fine but doesn't fire when using the ALTER SERVER ROLE [sysadmin] ADD MEMBER [Test]
Any ideas why it doesn't fire?
Using SQL2019 CU8
OK, found it after sifting through the intellisense and trying everything that looked right
FOR DDL_SERVER_SECURITY_EVENTS AS
