enric01 I assume you wish to refer to Post-installation message. Ref: Screenshot which appears to be more like typo.The specific module should work fine for J 3 version however, if some issue persists, You can always post here for assistance 🙂
Meanwhile, Will also confirm with JA Dev. Team if there are any sign of incompatibility
Please be patient while I revert back after getting update
Update - As also confirmed by JA Dev. Team that the specific module is compatible with J3 so you may kindly go ahead with configuring the same in J3 installation
