XSS Clean in CI4?

Sorry me, but let me ask showing an example:

In CI3 I clean the post with this method:
$post = $this->security->xss_clean($this->input->post(NULL, TRUE));

This means that all post received by the controller will pass by xss_clean. How I can do something like this on CI4?

There is no xss_clean function for CI4 because that is the wrong way to prevent XSS.

Here's some reading that may explain why the old CI approach is wrong and what you should do instead.
