Layered architecture should not be used

[tomazk8]

I would suggest not to use layered architecture inside clean architecture. Take vertical-slicing approach and build your solution around functionalities. One use-case = one functionality (mostly) and put things together that belong together (high cohesion). Don't group things by type (this is what layered architecture does). Otherwise you're bringing all the negative things from layered architecture into it so at the end there is no benefit, just more complexity.
