Are Modal Bottom Sheets not recommended on Wear OS? I don’t see one in the Wear Material Compose library.

The views library had some now deprecated sliding trays. But you are correct. Not recommended.

Not recommended by design. As a tip, in fact, the dialogs (confirmation, alerts) are built in a very differently way. https://www.composables.com/components/wear-compose-material/alert

Note that Alert and Confirmation format the content for your Dialog. You should still wrap that content in wear.compose.material.dialog.Dialog - the AlertDialogSample shows how you might do that.
