Triggering a twilio flow execution to the same number while another execution is still in progress will send a response of the same execution id without any indication that this execution is not a new execution:
This is the response of the first trigger of the execution:
{
status: 'active',
date_updated: null,
contact_channel_address: 'xxxxx',
account_sid: 'xxxx',
url: 'https://studio.twilio.com/v1/Flows/xxxx/Executions/FN519a25c6d932799cb8d1dc5bf78b489c',
context: {},

date_created: '2022-05-18T11:53:31Z',
contact_sid: 'xxx',

execution_context: 'https://studio.twilio.com/v1/Flows/xxx/Executions/FN519a25c6d932799cb8d1dc5bf78b489c/Context'
}
This is the response of the second trigger of the execution:
