Approval ads outside the playstore help!

Hello, late guys, I would like to know if anyone has an alternative to display ads to monetize applications outside the playstore, the request for approval to kodular is simply unfeasible because there are many apps, only 1 app the review waiting time is already over 1 month, whoever has an alternative or solution help me! thanks

I know you already have similar questions but I haven’t seen a viable solution for the situation of ad-dependent developers!
