HTML embedding in Zoho Analytics Dashboard

HTML embedding in Zoho Analytics Dashboard

Hello, 

I am attempting to embed social media posts in a dashboard, however this is proving tricky. 

For example, if I want to embed an Instagram post, I copy the embed code from Instagram, but the result looks like the attached screenshot "Instagram Embedding". Is there a way to get past this. I can provide the HTML code if requested. 

Further, when copying HTML code into analytics, sometimes this code is changed without permission. For example, attempting to embed the following: 

<iframe src="https://www.linkedin.com/embed/feed/update/urn:li:ugcPost:7073944086784679936" height="735" width="504" frameborder="0" allowfullscreen="" title="Embedded post"></iframe>

Becomes: 


<div>
    <iframe title="Embedded post" width="504" height="735" src="https://www.linkedin.com/embed/feed/update/urn:li:ugcPost:7073944086784679936" sandbox="allow-popups allow-forms allow-scripts allow-same-origin">
    </iframe>
    <br>
</div>

I was wondering why this is and what rules does analytics follow when dealing with HTML. Is there any documentation anywhere? 

A further question I have is to whether the HTML code can be changed dynamically. If I was to store URLs in a table in analytics, could I have the HTML code changed dynamically based on which URLs are in the table? 

Thanks for your help in advance.
