How to set update priority for a new android release

I have been trying to implement the Google’s new in-app updates and I am stuck at a point. The issue is first, how can the developer specify the type of update i.e. flexible or immediate while releasing a new update of the app. Secondly, if it's for the developer to decide which type of update he has to implement for a specific update then what is the use of – appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE) or appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.Flexible)

it is given in the documentation that Google Play uses an integer value between 0 and 5, with 0 being the default, and 5 being the highest priority. To set the priority for an update, use inAppUpdatePriority field under Edits.tracks.releases in the Google Play Developer API. how to set it?

Priority for app update can be set using Play Developer Publishing API's ⁠Edits methods. Currently there is no way to set it using Play Console but there is a plan to integrate in Play Console. Please look at this for more help, you will also find other helpful notes in this link. Hope it may help you

Here is the Google official guides https://developers.google.com/android-publisher/api-ref/rest/v3/edits.tracks/update

But i don't know how to run the API.

What are the parameters "editId" & "track" ? And what is the "Authorization Scopes" ?

Google really need to improve their documentation skills to make it crystal clear for developer like us
