How do we use Text Decorators?

I’m trying to use an image in the middle of a block of text, using SRichTextBlock (with a custom UWidget wrapper I’ve written for it). According to the documentation this is entirely possible, and I’ve found an FImageDecorator in code but don’t have a clue how to apply it or actually display the image.

By image, I’m assuming that means the block can only take UTexture2D assets as references? Or can I use materials too?

Some documentation would be appreciatted - but for now just some idea of how to use it would be nice!
