How to access the own dialog component after adding dialog to the service?

[domske]

Currently you add a dialog to the screen by:

const disposable  = this.dialogService.addDialog(DialogListComponent, {...}

But how set variables or call methods of the instance of the class DialogListComponent after created by the dialog service addDialog?

use case: Change the content of a dialog from another place but the dialog itself.

Current (one) solution: Add a parameter to pass a function and call this with argument this (this dialog instance) and have access to it.
