How to increase wordpress service upload file size?

by looking at wordpress service source code, I saw it use phpfpm, so I set the php config in services.phpfpm.pools.wordpress-{hostname}.phpOptions. I can confirm the value is in the config file passed to phpfpm with systemctl show phpfpm-wordpress-{hostname}, however wordpress still say the upload limit is 2M.

What can I do?

Never mind, I had a typo in the config name
