How to add suffix for all urls in codeigniter?

Question

CodeIgniter

Good afternoon!
Can you please tell me how to add a suffix for all urls in codeigniter 4.1.
I need to add a slash to the end for all urls - /
Previously, on older versions of codeigniter there was a setting - $config['url_suffix']
But on the new version it is not there and I don't quite understand how to do it correctly.
Can anyone come across and tell me how to do this?
