Successfully added resource gettweet locally.

Next steps:
Check out sample function code generated in <project-dir>/amplify/backend/function/gettweet/src
"amplify function build" builds all of your functions currently in the project
"amplify mock function <functionName>" runs your function locally
"amplify push" builds all of your local backend resources and provisions them in the cloud
"amplify publish" builds all of your local backend and front-end resources (if you added hosting category) and provisions them in the cloud
Succesfully added the Lambda function locally
? Restrict API access No
? Do you want to add another path? No
Successfully added resource api7168af60 locally

Some next steps:
"amplify push" will build all your local backend resources and provision it in the cloud
"amplify publish" will build all your local backend and frontend resources (if you have hosting category added) and provision it in the cloud

% amplify add function
? Select which capability you want to add: Lambda layer (shared code & resource used across functions)
? Provide a name for your Lambda layer: <layer名>
? Choose the runtime that you want to use: Python
? The current AWS account will always have access to this layer.
Optionally, configure who else can access this layer. (Hit <Enter> to skip) 
✅ Lambda layer folders & files created:
amplify/backend/function/nuxtamplifyicolablayer

Next steps:
Move your libraries to the following folder:
[Python]: amplify/backend/function/nuxtamplifyicolablayer/lib/python

Include any files you want to share across runtimes in this folder:
amplify/backend/function/nuxtamplifyicolablayer/opt

"amplify function update <function-name>" - configure a function with this Lambda layer
"amplify push" - builds all of your local backend resources and provisions them in the cloud
