Add own options to custom toast component

Hi, Today found one use case for passing custom options. In my case i want to pass icon name to component. It is actually possible with directly passing but there is errors about Object literal may only specify known properties, and 'toastIcon' does not exist in type 'Partial<IndividualConfig>'

Is there any workarounds for this ?

I’ve now looked at componentInstance, showing that it is undefined. Strange

const inserted = this.toastr.show('message', 'title');
inserted.toastRef.componentInstance.myProperty = 'something';

can access the component instance directly after creation
