Radzen IDE not all controls viewable for selection

Not all controls display so you can select and drag them to a form.
Namely I see many of the Graphs and SpeechToText are not there.

Am I missing something?

These components are available in Radzen Blazor Studio, in Radzen IDE can be used through CustomComponent:

Just specify the component name as Source (you should type it) and this will be rendered as tag name. To set properties you can use Attributes collection.

All chart and gauge components are included in the Radzen IDE toolbox. Different charts are implemented as different series types. Check the documentation for further reference.
