Change User side Dashboard

I recall seeing something on how to do this, but can't locate it in the docs. Just trying to add either a text box or an embedded video into the user dashboard. See attached photo.

do you change left to right in the code caesar?

i tried this to make a right and left

//add new block at position member/main/right
Am_Di::getInstance()->blocks->add(new Am_Block('member/main/right', 'google adverts', 'ad-R', null, 'renderMyBlock'));

function renderMyBlock() {
$html = <<<CUT
<p><script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- subs1 -->
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-xxxxxxxxxxx"
data-ad-slot="2848022103"
data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script></p>
CUT;
return $html;
}

//add new block at position member/main/left
Am_Di::getInstance()->blocks->add(new Am_Block('member/main/left', 'google adverts', 'ad-L', null, 'renderMyBlock'));

function renderMyBlock() {
$html = <<<CUT
<p><script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- subs2 -->
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-xxxxxxxxxxx"
data-ad-slot="2848022103"
data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script></p>
CUT;
return $html;
}

but i then get a white screen on the whole, site, what did i miss?

so if on right

Am_Di::getInstance()->blocks->add(new Am_Block('member/main/right', 'google adverts', 'ad-R1', null, 'renderMyBlock1'));

do i have to rename all the time the 3 parts? the ads, ad_r2 r3 ect and the block 1 2 3

or can i somehow add 3 banner codes in one block?

as this still gives a white screen

//add new block at position member/main/right
Am_Di::getInstance()->blocks->add(new Am_Block('member/main/right', 'google adverts', 'ad-R1', null, 'renderMyBlockR1'));

function renderMyBlock() {

//remove block with id member-main-unsubscribe

//add new block at position member/main/right
Am_Di::getInstance()->blocks->add(new Am_Block('member/main/right', 'google adverts', 'ad-R1', null, 'renderMyBlockR1'));
