HTML Editor image upload doesn't open

I'm sure I'm just missing something simple here.

I've updated to the latest nuget package for Radzen Blazor components, and I'm attempting to add the HTMLEditor to my page.

Most of it works, however clicking on the image upload button, nothing happens. The expected dialog box doesn't appear, i'm getting nothing appear in my output window, i'm not seeing any events in the developer console of my browser.

I'm sure I must have just missed something, but I have no idea what. Any hints would be appreciated.

---edit---

continued playing, still no progress, but the same issue appears to happen with the add hyperlink button. at a guess it's something to do with the dialog service, but I've got

services.AddScoped<DialogService>();
services.AddScoped<NotificationService>();

in my startup file,

---edit---

Figured it out eventually.

had to add

@using Radzen.Blazor
<RadzenDialog /> 
<RadzenNotification />

to my mainlayout. This isn't mentioned anywhere in the documentation, so may need adding there at some point.

I know I should probably put a new topic up for these follow up questions but since I answered this one myself may as well ask here.

What's the best readonly panel for viewing the content in a rich text box. (imagine I'm making a blog or something similar.) is there anything Radzen provides like an html parser for this kind of thing?

It is in the getting started instructions.

The best readonly panel is the <div> HTML element. Just show your content there.

<div>
@((MarkupString)myPropertyThatContainsHtml)
</div>

Radzen does not provide an HTML parser but I don't think it is needed to display HTML.
