How can I suppress the message `When done with this frame, type C-x 5 0`?

Question

I am running emacs v26 daemon on the background and using a single terminal. Usually I open files using emacsclient -qt and close them using C-x C-s and C-x C-c to get back to terminal run the script and afterwards re-open another file.

I wanted to make this operation faster where when I run emacsclient -qt -e '(progn (find-file "file.py"))' seems like it opens the files much faster than emacsclient -qt file.py (this may lag to show previous buffers for a second).

But now, when I run emacsclient -qt -e '(progn (find-file "file.py"))' I keep seeing When done with this frame, type C-x 5 0 message in the minibuffer.

=> How can I suppress this warning message? and also safe to open files this way?

Not perfect but the script I come up with:

#!/bin/bash

open_emacs() {
    FILE=$1
    if [[ -d $FILE ]]; then
        echo "Folder path is provided, please provide a file"
        return
    fi

    if [ ! -f "$FILE" ]; then
        echo "$FILE does not exist."
        return
    fi

    if [ "$#" -ge 1 ]; then
        emacsclient -qt -e '(progn (find-file "'$FILE'"))'
        if [ $? -eq 0 ]; then
            true
        else
            emacsclient -qt -e '(progn (find-file "'$FILE'"))'
        fi
    else
        echo "## Please provide a file"
    fi
}

open_emacs file.py

This is possible starting from Emacs 28, which provides the user option server-client-instructions for this purpose.

(setq server-client-instructions nil)
