Invoke a lambda function with deployment using serverless framework

Question

Is there a way to invoke a lambda function immediately after deployment using serverless framework. This function just creates the SNS Application, which is required to be done once only during setup. I can use serverless deploy stage && serverless invoke --function functionName but that won't tear down the setup if the function fails.

I want it to be deployed as part of setup.

Thanks

Hooks can be added to the lifecycle events of the Serverless framework.

I used serverless-plugin-scripts plugin(https://www.npmjs.com/package/serverless-plugin-scripts) to invoke custom jobs after deployment and removal of stack.

Here is an example -

custom:
  scripts:
    hooks:
      'deploy:finalize': sls invoke -f functionName && 
      'remove:remove': npm run scriptName && sls invoke -f anotherFunctionName

Now, after successful deployment via serverless deploy, sls invoke -f functionName is triggered.

Similarly, on removal using serverless remove, npm run scriptName && sls invoke -f anotherFunctionName executes.
