Reading the doc, to implement ironSource as a mediation waterfall on AdMob we have to add com.google.ads.mediation:ironsource:7.2.7.0 but this repo have a dependency to com.ironsource.sdk:mediationsdk:7.2.7 which does not exist https://mvnrepository.com/artifact/com.google.ads.mediation/ironsource/7.2.7.0
I maybe have the wrong approach to install it
