I would like to add a RTE in a custom dashboard in the Backoffice. It could be awesome if I could add a text-area (using one of Umbraco UI elements). But is it possible to use a userdefined datatype from the settings? For example it could be a dataype where the property editor one day is TinyMCE RTE and another day changed to TipTap RTE. But no changes has to be done in the dashboard code. Has someone a hint where I should look or maybe an idea of what to extend/import in my dashboard?

THE Matt Brailsford has written an article about this: https://mattbrailsford.dev/reusing-umbraco-properties-in-umbraco

Looks like exactly what I was looking for. Thanks.
