Multple Method in 1 resource in 1 path

Does it possible to implement this?

/satellites --> GET --> LAMBDA-A-NJS (have already)
/satellites --> POST --> LAMBDA-B-NJS

Configure :

 apiGateway:
      restApiId: xxxxxx
      restApiRootResourceId: zzzzz
      restApiResources:
        satellites: aaaaaa

Event :

 -   http:
                    path: satellites
                    method: post

It doesn’t work

The method already exists for this resource
