Integration of admob into an sketchware-made app

Hi everybody! I have made some apps with sketchware and published 'em in google play store. For example:
(play.google.com) /store/apps/details?id=com.dk.timetravel1_0

(play.google.com) /store/apps/details?id=com.dk.tabtabsnowfox

(play.google.com) /store/apps/details?id=com.dk.zeitreise1_premium

I already have advertising in it (not from google), the ads are running in a webview window.

Now to my question: I am trying for weeks to activate google admob in my apps. I was already able to export/import my sketchware-made app into android console and activate the build.gradle BUT then some files, that were mentioned in tutorials, were missing and i couldnt proceed all tutorial steps.

So, please, could anybody tell me where to find or just show me a step by step tutorial:

How to export/import a sketchware-made app into android console, and to activate admob inside that already finished sketchware-made app. (Maybe with the option to reopen it later in sketchware again and work on on it). That woukd be great thx.

Jeah that's no problem (app is already finished) and as i wrote i was able to export it and build up the gradle stuff...but i could not proceed with the necessary steps to integrate admob... thats why i am asking for an tutorial...or is it not possible to activate admob in sketchware projekts, at all?
