REceiving SQL erro 37000 after attempting to run Script creating Trigger

Question

I'm attempting to create a trigger using DBEAVER and Intersystems Cache Database using the following statement:

CREATE TRIGGER AFTER INSERT trigger1
    ON System.get_table1
    
AS
BEGIN
    SELECT * FROM System.get_table2 
END; 

and im getting this error:

SQL Error [1] [37000]: [SQLCODE: <-1>:<Invalid SQL statement>]
[Location: <Prepare>]
[%msg: < 'BEFORE' or 'AFTER' expected, INSERT found^CREATE TRIGGER AFTER INSERT>]

I've attempted moving the AFTER INSERT around and it doesn't seem to be working.
