aws cdk deploy lambda function to mutiple region

Currently, I have my code pipeline set up, and it just deploy the stack and the lambda function to the region(ap-north-east) in which I have set up in the aws config in AWS CLI. How can I create another action that in the same deploy stage which can deploy the lambda function to ap-south-east. I can reproduce this in AWS console, but not sure how to make it in CDK

Here is my pipeline code

This is my pipeline stack

import * as cdk from 'aws-cdk-lib'
import { Construct } from 'constructs'
import * as codecommit from 'aws-cdk-lib/aws-codecommit'
import { DbcallPipelienStage } from './pipeline-stage'
import { CodeBuildStep, CodePipeline, CodePipelineSource } from 'aws-cdk-lib/pipelines'


export class DbCallPipelineStack extends cdk.Stack {
    constructor(scope: Construct, id: string, props?: cdk.StackProps) {
        super(scope, id, props)

        // Creates a CodeCommit repository called 'dbcallRepo'

        const repo = new codecommit.Repository(this, 'dbcallRepo', {
            repositoryName: 'dbcallRepo'
        })

        // The basic pipeline declaration. This sets the initial structure
        // of our pipeline

        const pipeline = new CodePipeline(this, 'Pipeline', {
            pipelineName: 'WorkshopPipeline',
            synth: new CodeBuildStep('SynthStep', {
                input: CodePipelineSource.codeCommit(repo, 'main'),

                installCommands: [
                    'npm isntall -g aws-cdk'
                ],
                commands: [
                    'npm ci',
                    'npm run build',
                    'npx cdk synth'
                ]
            })
        })
 // Below is creating the deploy stage and add an action
        const deploy = new DbcallPipelienStage(this, 'Deploy');
        const deployStage = pipeline.addStage(deploy)
    }
}

This is my pipeline stage which is try to instantiate my lambda stack

import { Stage, StageProps } from 'aws-cdk-lib'
import { CdkTestStack } from './cdk-test-stack'
import { Construct } from 'constructs'



export class DbcallPipelienStage extends Stage {
    constructor(scope: Construct, id: string, props?: StageProps) {
        super(scope, id, props);


        new CdkTestStack(this, 'dbcall')

    }
}
