System i SQL stream file from IFS - sql

Question

IBM System i V7R3M0 I would like to pull a .json file with SQL. The SQL cannot resolve QSYS2.IFS_READ.
select x.id, x.username, x.firstName, x.lastName, x.email
from json_table(
QSYS2.IFS_READ(PATH_NAME => '/FileTransferData/userList.json'),
'lax $' columns (
id INTEGER PATH 'lax $.id',
username VARCHAR(30) FORMAT JSON PATH 'lax $.username',
firstName VARCHAR(30) FORMAT JSON PATH 'lax $.firstName',
lastName VARCHAR(30) FORMAT JSON PATH 'lax $.lastName',
email VARCHAR(75) FORMAT JSON PATH 'lax $.email'
)
)
as x;
The error is:
SQL State: 42704
Vendor Code: -204
Message: [SQL0204] IFS_READ in QSYS2 type *N not found. Cause . . . . . : IFS_READ in QSYS2 type *N was not found.
The job log in QZDASOINIT tells me the same thing, that I do not have IFS_READ in QSYS2

I'm between a rock and a hard place. My outsourced support company claims that
I need to create a program to utilize the API. However, I believe the API is not installed.
I have based my work on IBM technical documents such as this:
https://www.ibm.com/docs/en/i/7.4?topic=is-ifs-read-ifs-read-binary-ifs-read-utf8-table-functions
Running the example in this document (with file path and name changed to mine) give the same error.
SELECT * FROM TABLE(QSYS2.IFS_READ(PATH_NAME => '/FileTransferData/userList.json', END_OF_LINE => 'CRLF'));

This link indicates PTF SF99703 level 22 is required. You can check what's installed or available with :
with iLevel(iVersion, iRelease) as (
select
OS_VERSION, OS_RELEASE
from
sysibmadm.env_sys_info )
select
case PTF_GROUP_CURRENCY when 'INSTALLED LEVEL IS CURRENT' then '' else PTF_GROUP_CURRENCY end,
PTF_GROUP_ID "ID",
PTF_GROUP_TITLE "Title",
PTF_GROUP_LEVEL_INSTALLED "Installed",
PTF_GROUP_LEVEL_AVAILABLE "Available",
ptf_group_level_available - ptf_group_level_installed "Diff",
date(to_date(PTF_GROUP_LAST_UPDATED_BY_IBM, 'MM/DD/YYYY')) "Available since",
current date - date(to_date(PTF_GROUP_LAST_UPDATED_BY_IBM, 'MM/DD/YYYY')) "Days since available",
PTF_GROUP_RELEASE "Release",
PTF_GROUP_STATUS_ON_SYSTEM "Status"
from
iLevel,
systools.group_ptf_currency P
where
ptf_group_id = 'SF99703'
order by
ptf_group_level_available - ptf_group_level_installed desc;
