Change font size for ion-searchbar input in Ionic 5

How do I change the font size of ion-searchbar input? Could anyone please help.

<ion-searchbar></ion-searchbar>

Here's what I tried but this does not work

.searchbar-input {
  font-size: 10px;
}

Please refer to the working example which I created in Stackblitz

In Ionic 5

global.scss

ion-searchbar {
    .searchbar-input-container {
        input{
            font-size: 14px !important;
        }
    }
}
