Can't save report to different workspace - saveAsTriggered not firing in powerbi embedded - event-handling

Question

I am trying to create a new report in power bi embedded and save the report to a workspace that is DIFFERENT from the dataset its using I am setting up the embed token correctly - using the V2 token requests for both the dataset and workspaces but click the SaveAs in the embedded UI returns an "unable to save report" failure.
I believe what's missing is that I need to set the targetWorkspace in the SaveAs parameter. To do that I need to watch the saveAsTriggered event and in there specify the targetWorkspaceId.
However the saveAsTriggered event is never firing! Even in power bi playground the event does not seem to be firing - see code example below.
I am assuming that the saveAsTriggered event should fire even when using the embedded "Save As" button and not only if I call saveAs via the API?
In any case the event is never firing and I have no way to set the target workspace for the report to save As.
If anyone can advise another way to specify the target workspace when setting up a custom saveAs OR a way to get the saveAsTriggered event to fire, it would be very much appreciated.
Thanks
I used the code below in power bi playground: https://playground.powerbi.com/en-us/dev-sandbox
// Embed a Power BI report in the given HTML element with the given configurations
// Read more about how to embed a Power BI report in your application here: https://go.microsoft.com/fwlink/?linkid=2153590
function embedPowerBIReport() {

Figured it out. I needed to modify the embed config to include
settings: {
useCustomSaveAsDialog: true
}
Then you do need to use your own Save As Modal but then at least the saveAsTriggered will fire!
