Open IonSelect Programatically in Ionic-Vue App

Question

We have an Ionic-Vue App (Ionic 6 and Vue 3) and try to open an IonSelect programmatically. We tried using a ref like this:

 <ion-select ref="mySelect" placeholder="something" v-model="selectedIndex">
     <ion-select-option :value="1">One</ion-select-option>
     <ion-select-option :value="2">Two</ion-select-option>
 </ion-select>

and we can indeed access it like this:

myMethod(){
    console.log(this.$refs.mySelect);
}

but we cannot figure out any way to open it. According to the ionic documentation [1] there should be an open() method, but

this.$refs.mySelect.open()

crashes with "... is not a function" so this does not seem to cut it. Any help is appreciated.

UPDATE:

Found it. In case someone is looking for this, access the ion-select via

this.$refs.mySelect.$el.open();
