Get uploaded file data in CI 4

In Codeigniter 3, $this->upload->data(); does it. In documentation of CI 4, I found some functions for getting specific uploaded file data like, getName(), getClientName(), getClientMimeType() etc. But how can I get all the uploaded file data at once like CI 3?

I am using $file->store(); to upload file.

Thanks in advance.
