Passing variables to email footer in Laravel

Question

I would like to show a disclaimer in the footer saying

This email was sent to {recipients email address}.

but i can't figure out how i can get the email address into the standard footer blade.

Here is what I have: In my notification component I make the following call with $rcp_email having the email address of the recipient:

return (new MailMessage)
            ->subject('Contact Form Submitted')
            ->markdown('emails.generic.contactform', [
                'first_name' => $this->first_name,
                'message' => $this->message,
                'rcp_email' => $this->rcp_email,
                'url_security_issue' => $url_security_issue,
            ]);

The emails.generic.contactform looks like this

@extends('emails.main')
@section('content')
(body of email)
@endsection

emails.main looks like this

@component('mail::message')
@yield('content')
@if (isset($unsubscribe_url))
(html code for unsubscribe)
@endif
@endcomponent

the standard vendor\mail\html\message blade looks like this:

@component('mail::layout')
{{-- Header --}}
@slot('header')
@component('mail::header', ['url' => config('app.front_end_url'), 'logo' => asset('logo-image-white-circular-background.png')])
{{ config('app.name') }}
@endcomponent
@endslot
{{-- Body --}}
{{ $slot }}

{{-- Subcopy --}}
@isset($subcopy)
@slot('subcopy')
@component('mail::subcopy')
{{ $subcopy }}
@endcomponent
@endslot
@endisset

{{-- Footer --}}
@slot('footer')
@component('mail::footer')
 © {{ date('Y') }} {{ config('app.name') }}. @lang('All rights reserved.')
@endcomponent
@endslot
@endcomponent

I traced each level of blade and $rcp_email is first of all not availble in the message blade. I tried to pass it on by changing the first line of emails.main to

@component('mail::message', ['rcp_email' => $rcp_email])

but in either case when i try to use the variable in the message blade, i get the error Undefined variable: rcp_email

In an ideal case, I would want to add the html code and make use of the variable in the actual footer blade, but I don't know if that's possible.

I would much appreciate if there is any hints/any docus or articles you can share that describes in depth how this works?
