How to embed Sitemap from Canva without opening links in new tabs?

[gwretling]

I´ve created a sitemap in Canva (canva.com) and embedded that code in the html editor in Canvas. The sitemap shows up in Canvas and works fine except when clicking the links in the sitemap - everything open in new tabs. Any solution for that? Nothing changes when using target="_self" instead of target="_blank" 

The embedded code from Canva
<div style="position: relative; width: 100%; height: 0; padding-top: 75.0000%;
padding-bottom: 48px; box-shadow: 0 2px 8px 0 rgba(63,69,81,0.16); margin-top: 1.6em; margin-bottom: 0.9em; overflow: hidden;
border-radius: 8px; will-change: transform;">
<iframe style="position: absolute; width: 100%; height: 100%; top: 0; left: 0; border: none; padding: 0;margin: 0;"

</iframe>
</div>
