Email from Google about Migrate to the Play Install Referrer API by March 1, 2020

Hi,

I received an email notification from google that I need to migrate to the Play Install Referrer API by March 1, 2020, for almost all of my apps. I just use this AdMob plugin and no other third party plugins, I also don't use Firebase. So I think this is somehow related to the AdMob plugin. I use the latest version (v4.1.0). I found out after reading some places that it is related to the permission "INSTALL_REFERRER" or "BIND_GET_INSTALL_REFERRER_SERVICE". But I can't figure out how these are added to my manifest file. Are these added by the AdMob plugin? If so then are you going to release an fix before March 1, 2020? Please let me know.

Below is the email I received from Google:
Hello Google Play Developer,
We recently announced that we’ll be deprecating the install_referrer intent broadcast mechanism. Because one or more of your apps uses this intent to track referrals, we wanted to ensure you make the switch before March 1, 2020. After this date, new versions of the Play Store app will no longer broadcast the install_referrer intent after app installs.

Action required
Migrate to the Play Install Referrer API to track your app installs for the following apps and/or games.
