Hi!
You can already configure your Next adapter to create slice with the ````jsx extension
You need to update your `slicemachine.config.json with:
"adapter": {
"resolve": "@slicemachine/adapter-next",
"options": {
"jsxExtension": true
}
},
Documentation: @slicemachine/adapter-next Technical Reference - Documentation - Prismic
Let us know if it solves your problem.
