CMS Collections, used for blog, adding a GIF?

We transferred an old website to Webflow. We had a blog and are now using the CMS Collections for this now. One post imparticular had a ton of GIFs on them. Now, I am trying to figure out how to post a GIF within the post content since I am not finding a WYSIWYG tool bar.

Do I just use an embedded link from GIPHY?

Or is there a special tool? Not sure why some showed up and some didn’t to be honest.

Thanks in advance for the help.
