NoSuchElementError for Android Appium locators

Question

I am using Appium 1.22.3 and webdriverIO5 for Android mobile automation The DOM for the element I am trying to click on is as below:

<android.widget.Button content-desc="Sign in">

I have used different combinations of locators as below:

await $('android.widget.Button');
driver.elementsByAccessibilityId('Sign in');
$('Sign in');
$('id=Sign in')
findElementByAccessibilityId("Sign in"); 
dr.findElementByAccessibilityId("Sign in")

However none of these xpaths work and I get error as below:

Appreciate any help on how to identify the correct locator here

Thanks. I was able to use let el = await $('//android.widget.Button[@content-desc="Sign in"]'); successfully finally!
