Im running a Modpack with a few mods that also use the Trinkets mod. Unfortunately Inventorio (Fabric 1.20.1) doesn't seem to be compatible with it. I feel like this is one of those mods that it really should be compatible with.

You can access the Trinkets menu by pressing a toggle in the top-right corner. It takes you from Inventorio menu to vanilla inventory menu, which trinkets modifies.
Other than that there's no good solution for it sadly.
Also, this ticket a duplicate.
