[Dor-bl]

refer to: appium/java-client#1571

@mykola-mokhnach , we need to implement this, right?

[mykola-mokhnach]

right, this set of APIs will be eventually removed from the server: appium/appium#15807

[Dor-bl]

@mykola-mokhnach can we close this or should I wait for appium/appium#15807 to be closed?

Should be ok, thank you
