You can now define a “custom _id” while uploading the app to LambdaTest cloud servers.
With the “custom_id”, you can run app automation on the same app.
Shown below is the cURL request with custom _id 
curl --location --request POST 'https://manual-api.lambdatest.com/app/upload/realDevice' \
--header 'Authorization: Basic <Basic Auth Code>' \
--form 'name="\"lambda1\""' \
--form '[email protected]"LambdaTest.apk"' \
--form 'custom_id="LambdaTest"'
