How to send data from IoT Core rules to IoT SiteWise

Hi everyone, I'm relatively new on AWS. I currently receive data in a Rule in IoT Core (MQTT) using SDK in the information source. This data needs to be send to IoT SiteWise to trade it. In the AWS SiteWise manual, I have seen ways to do that using Greengrass, but I cannot use this option (company politics). I tried to do what it's explined in the folloing link: https://iot-sitewise.workshop.aws/en/40_aws-iot-sitewise-data-ingestion/ingest-data-through-iot-core.html The problem is that, on that link it doesn't explain how to configure an IAM role. I also found this link: https://repost.aws/questions/QUbrB4L4GdTNinE1kxZ0PFqw/problem-with-ingestion-data-from-iot-core-mqtt-to-aws-sitewise But in my opinion, it's not completely answered. I have also found information about Device Shadow, but in my case, I prefer to use the Rule, thus I already receive information there, and I have not understood the way to install the "connect the device package" in my device. How can I take the values from my Rule (or it can be also from S3) and trend it in IoT SiteWise?

Thanks.
