How to pass multiple parameters to outlet route?

Question

Angular

Now the code looks like this, with one parameter:

<a
                                        [routerLink]="[
                                            '/',
                                            {
                                                outlets: {
                                                    primary: ['docudo', r.documentnumber],
                                                    sidebar: ['docudo']
                                                }
                                            }
                                        ]"
                                        >{{ r.documentnumber }}</a
                                    >
