Tap on SwiftUI LocationButton in UI Test

I am unable to tap on the LocationButton in a Swift UI Test. This is the button:

I am in a breakpoint in a UITest and I tried this without luck:

• app.buttons.count returns 0
• app.staticTexts["Current Location"].exists returns false
• app.buttons["Current Location"].exists returns false

Is there something special about this button? How can I tap it in a UITest?
