Difficulty Adding Content to Interactive Legend

[SanctuaryFarms]

Hello! I'm currently using Arcgis Online and having trouble finding how to add content to my interactive legend. 

We have a folder of personalized icons that we want to use, and we want to be able to click on each icon in our interactive legend and only have those corresponding places appear on the map. 

I am having difficulty finding the option to add these image icons to our interactive legend, specifically finding the way to access the "Contents Pane" and its layer to be able to drag it to the "Legend Group". I chatted with Esri AI chatbot support but still cannot find these options and am having difficulty navigating the interface.

Are there any specific video tutorials that I can follow? Or other recommendations? Please let me know, we appreciate the help!

@SanctuaryFarms Interactive Legend pulls in the symbology and legend from the map. To use a custom image in Interactive Legend, you will need to configure it in the map first. Here is a blog showing how to do that. Once the map legend looks how you want it, you can create the Interactive Legend Instant App. Interactive Legend does only supports specific drawing styles. For a complete list of what is supported, visit the doc.
