Response on button click?

Question

Bots

There is a bot shop on the wokomerc
, in it you need to add a button, when clicked, text information will be displayed (contact for example)

private function bftow_get_default_keyboard()
    {
        $keyboard = [
                        ['text' => 'Кнопка 1',],
                        ['text' => $this->shop_button,],
                    ];
        
        if ($this->fast_checkout === 'no') {
            $keyboard[] = [
                'text' => $this->cart_button,
            ];
        }
        return apply_filters('bftow_default_keyboard', $keyboard);
    }

so I added "Button 1" to the code - which is displayed in the bot
when clicked, it returns the text "Button 1"

what needs to be written there so that when clicked it displays "tel: [phone]" I got tired

of looking in the net - a lot of information, the jug has already cracked
