i granted the dtest proxy to account CCFAPP.
alter user ccfapp grant connect through dtest;

USER is "DTEST"

SQL> comment on column ccfapp.tcodes.prog_type is 'program types';

                         *

Consider to learn how to simply Read The Fine Manual yourself.

GRANT CONNECT in & of itself does NOT all you to manipulate any OBJECT; only to connect to this instance.

In Oracle EVERYTHING is forbidden; except that which is explicitly GRANTED.

https://docs.oracle.com/database/121/SQLRF/statements_4010.htm#SQLRF01109

"Prerequisites

The object about which you are adding a comment must be in your own schema or:

To add a comment to a table, view, or materialized view, you must have COMMENT ANY TABLE system privilege."

This doesn't add up. If you login as dtest[ccfapp] you are logging as ccfapp through dtest and therefore SHOW USER should return CCFAPP, not DTEST. For example, I create user U1 and grant it proxy access as scott:

SQL> drop user u1 cascade;

User dropped.

SQL> create user u1 identified by u1 default tablespace users;

User created.

SQL> grant create session to u1;

Grant succeeded.

SQL> grant select on emp1 to u1;

Grant succeeded.

SQL> connect u1@pdb1sol122/u1
Connected.
SQL> comment on column scott.emp1.ename is 'employee name';
comment on column scott.emp1.ename is 'employee name'
                        *
ERROR at line 1:
ORA-01031: insufficient privileges


SQL> connect scott@pdb1sol122
Enter password: *****
Connected.
SQL> alter user scott grant connect through u1;

User altered.

SQL> connect u1[scott]@pdb1sol122/u1
Connected.
SQL> show user
USER is "SCOTT"
SQL> comment on column scott.emp1.ename is 'employee name';

Comment created.

SQL> 

As you can see, SHOW USER returns SCOTT, not U1.

SY.

In this case you should have another message:
SQL> create user act1 identified by act1;

User created.

SQL> grant create session to act1;

Grant succeeded.

SQL> create user proxyone identified by proxy1;

User created.

SQL> grant create session to proxyone;

Grant succeeded.

SQL> alter user act1 grant connect through proxyone ;

User altered.

SQL> alter user act1 account lock;

User altered.

SQL> connect proxyone[act1]/proxy1
ERROR:
ORA-28000: the account is locked
