how to change logo at android?

[eunseoDev]

I am experiencing an issue on an Android device (Samsung S21).
I am already using the Firebase Messaging service. I am using a custom icon and have set it in the notification.
However, when I initialize CallKit, the notification icon changes to the 'callkit' logo.
Now all notification's icon shows 'Callkit' logo...
Is there a way to set the icon like in the iOS parameters, or is there another method? Am I missing something?
