Android appium Permission Denial: starting Intent

Anyone can help me to see this permission issue is due to the app which I need developer to re-build with permission open? or it is my adb command issue? or the intent argument is used wrongly?

At android phone,

1st screen: com.ninetest.hd3.test.testDetectActivity

2nd screen:

com.ninetest.hd3.activity.MailActivity

When executing adb command with 1st screen, error occurred. if I changed the appActivity to 2nd screen then no issue. but i cannot skip first screen if I need to run appium test cases.

I cannot skip the intent argument as well, otherwise the app which installed under work profile is not launced.

**error**

C:\Users\tester>adb shell am start --user 10 -n "com.ninetest.hd3.work.cac/com.ninetest.hd3.test.testDetectActivity"

I think You need to set android:exported="true" in your AndroidManifest.xml file in your Activity
