URGENT HELP with revmob (Its easy)

Hello, I put revmob before of local scene = storyboard.newScene()

I put this before:

local RevMob = require(“revmob”)

local REVMOB_IDS = { [“Android”] = “On here my app id” }

RevMob.startSession(REVMOB_IDS)

And after in some sites the RevMob.showFullscreen()

Its true?

With  RevMob.setTestingMode(RevMob.TEST_WITH_ADS) see good but I don’t know if is true for release, the user could see the ads right? I publish my game and I don’t know if is right before os newScene or if not have nothing for see these.

Thanks in advance!
