I am in the final steps of my email flow via Power Automate. It was a long road because I had to learn a little about that capabilities of Power Automate. Apparently sending attachments are not straight forward in flow, but the good guys at ESRI have created a tutorial on how to send attachments. The good, this tutorial is straight forward. The bad, you would need Power Automate Premium to complete this task. I have researched work arounds for this, but at the end of the day, I submitted a request for Premium to be added to my account. Tutorial link is below.
