Creating a Trigger for grants post table creation

Hello Everyone

We have inherited an Oracle 19 database and there are 4 schemas in database called USER_A,USER_B,USER_C,USER_D

What we are trying to accomplish is to create a trigger that fires when:

A table is created in either of those 4 schemas
The logged on user connected to the database creating the tables under those 4 schemas could be any user with DBA privs like SYS or SYSTEM etc
As soon as the table is created, we want this following SQL to be executed

Select ' Grant select,update,delete,insert on '||OWNER||'.'||TABLE_NAME|| ' to TAB_FULL_ROLE ' ||';'
