BitBar Execution - Maximize browser window irrelevant or browser selected

We are using Test Complete to execute our tests on bitbar. we use Edge ,Chrome and Safari as our browsers under test. The question is : using TestComplete, how do we send the maximize browser call and have it work across all the browsers used for testing in BitBar Cloud?

We have tried: Aliases.browser.BrowserWindow.Maximize() => this works locally but not on BitBar.

Any suggestions to try out?
