How to use all methods of PHP Redis with Codeigniter 4

Hi all

I am trying to use redis cache in Codeigniter 4 with PECL PHP REDIC . 

Codeigniter 4 documentation shows only few methods like GET, SAVE, DELETE. 

I tried to use SET but it did not work. How to use all available methods of PHP REDIS like set, hSet, etc?

Regards
