How to copy table using the procedure that gets the table's name to copy and name of the new table to create it in Pl/SQL oracle?

Question

Running the following code

create or replace procedure copy_table(
        from_table in out varchar2,
        new_table_name in out varchar2
    ) is v varchar(4000);
begin
    v :='create table new_table_name as select * from from_table';
    execute immediate v;
end copy_table;

begin
copy_table(lalala, new_table);
end;

I got the error

begin
copy_table(lalala, new_table);
end;
Error report -
ORA-06550: line 2, column 12:
PLS-00357: Table,View Or Sequence reference 'LALALA' not allowed in this context
ORA-06550: line 2, column 1:
PL/SQL: Statement ignored

How to correctly call the procedure since I alredy have "lalala" table? And will my procedure work for coping the existing table and create a new one? Or the code is wrong?
