Soaked in water and connected to charger

Today, while I was washing my hands, my samsung s9 slid into the sink and got pretty soaked. I thought since the phone was water resistant I didn’t care too much and connected it to a charger right after as it was low on battery. It was later that day that I realised my mistake. The phone still charges and works but I am not sure if there are any sort of internal damage from connecting the wet phone to charger. If they are some possible damages, i might get the phone checked a samsung store and exchanged as it is covered by samsung protection plus warranty.
