Как убрать вложенность промисов?
вот такthis.$store.dispatch(GET_ORDER, order).then(() => {
    let data = {};
    data.id = order;
    data.order = {
        status,
        comment,
        totalPrice,
        paymentMethod
    };
    return this.$store.dispatch(PATCH_ORDER, data);
}).catch(() => {
    return this.$store.dispatch(POST_ORDER, {
        id,
        status,
        comment,
        totalPrice,
        paymentMethod
    });
}).then(() => {
    if (this.responseServer) {
        this.$refs.modalSend.hide();
        this.status = 1;
    }
});
Переписать на async/await ?
