how to print all emenet of value_of_lossy

I'm trying to print all the argument of a command

 let text_output= matches.value_of_lossy( "text").unwrap();

but it just print the first element for example if i write

    cargo run -- hello world
the output = hello

the src code :

use clap::{App, Arg};
fn main() {
    let matches = App::new("echo")
        .version("1.0.0")
        .author("unknown")
        .about("echo Command with Rust")
        .arg(
            Arg::with_name("text")
                .value_name("TEXT")
                .help("input text")
                .required(true)
                .min_values(1),
        )
        .arg(
            Arg::with_name("new_line")
                .short("n")
                .help("don'tmake a newLine")
                .takes_value(false),
        )
        .get_matches();
    
    let text_output= matches.value_of_lossy( "text").unwrap();
    let new_line = matches.is_present("new_line");
    let  ending = if new_line{""}else{"\n"};
   
         print!("{}{}", text_output, ending);
    
}

i try :

print!("{}{}", text_output.join(" "), ending);

and i get this err :

^^^^ method not found in `Cow<'_, str>`
