Hello @Olivier Manso ,
You could check Invoking Events from Effects in Xamarin, it explains the platform touch events. Then you can refer to Migrating Xamarin.Forms Effects to add the effect into MAUI.
In addition, there is a proposal to include this in the MAUI Community Toolkit- Proposal TouchEffect #86, it is expected to be implemented in MAUI Community Toolkit. And there is a known issue- TouchEffect not working #1905, you could refer to the workaround and follow the progress.
Best Regards,
Wenyan Zhang
