Twitter doesn't allow embedding tweets from their platform through an iFrame. Since the embed widget functions as an iFrame within your dashboard and reports, you can use services like Twitframe to work around this limitation.
How to embed tweets
To embed a tweet using the embed widget, get the post's link by using the "copy link to tweet" option on Twitter.
Next, use the code below and replace the bold text with the tweet link you just copied:
<iframe border=0 frameborder=0 height=250 width=550
Here's a sample embed link for a tweet that should work with the embed widget:
<iframe border=0 frameborder=0 height=250 width=550 src="https://twitframe.com/show?url=https://twitter.com/abramarketing/status/1507410145881444362?s=20&t=GrVuuUU1OtpPrszgencMAA"></iframe>
Add this code to your embed widget by clicking the ellipsis “…” in the top right-hand corner of your embed widget and selecting “Edit”.
Change the Type to iFrame, take the URL, and paste it into your embed widget's iFrame box. Click the "Save" button to add the widget to your dashboard or web report.
You can then resize the widget to adjust the size of the tweet.
