merge two ParamMap angular

I have the following code that works fine:

let urlParameters = combineLatest(
[this.route.params, this.route.queryParams], (params, queryParams) => ({
...params, ...queryParams
}));

urlParameters.subscribe(params => {
console.log(params["type"]);
});


in the result I have new object and can access as params["type"]

but can I do the same with queryParamMap and paramMap? like:

let urlParameters = combineLatest(
[this.route.paramMap, this.route.queryParamMap], (params, queryParams) => ([
...params, ...queryParams
]));

urlParameters.subscribe(params => {
console.log(params.get("type"));
});


and I can use ParamMap methods like params.get("type")
