Where is HostDialogService?

[maasha]

As documented here:

https://learn.microsoft.com/en-us/azure/devops/extend/develop/using-host-dialog?view=azure-devops

Apparently only HostPageLayoutService is available, but the dialog provided here lacks options for configuring size and buttons.

"azure-devops-extension-api": "^4.246.0",

This

import * as SDK from 'azure-devops-extension-sdk';
...

        const dialogOptions = {
          width: Math.floor(window.screen.width * 0.9),
          height: Math.floor(window.screen.height * 0.9),
          title: dialogTitle,
          okText: "OK",
          cancelText: "Close",
          okCallback: (result: any) => {
            //do something
          }
        };

        // Get the extension context to build the dialog contribution ID
        const extensionContext = SDK.getExtensionContext();
        const dialogContributionId = `${extensionContext.id}.dialog-name`;

        // Open the print dialog using the dialog service
        //TODO: Should be IHostDialogService
        const dialogService = await SDK.getService<any>('ms.vss-web.dialog-service');
        await dialogService.openDialog(dialogContributionId, dialogOptions, contextForDialog).then((dialog: any) => {
          dialog.updateOkButton(true); //Enable OK / Print 
        });

works with
"azure-devops-extension-api": "^4.259.0",
"azure-devops-extension-sdk": "^4.0.2",

However, i also cant find the type in repos and have fallen back to using any.
