Send Image through Power Automate

Hi! I'm struggling a bit trying to allow a user to take or upload a photo, but then send it through to Power Automate for further processing...

The OnSelect of my send button (btnSend) looks like this, currently:

Set(varUserId, User().Email); // or any other user identifier
Set(varImageJSON, JSON(UploadedImage2.Image, JSONFormat.IncludeBinaryData));
Set(varImageBase64, varImageJSON);
HRPhoto.Run(varUserId, varImageBase64);

I figured Base64 was my safest bet but cannot get it to flow into Power Automate... when it's just the userId field as a Trigger Condition, it works fine.  My end game will be to use Power Automate to route the image through a developer Adobe Express API for reduction and file conversion and then into SharePoint to be used to create an ID Badge.  
 
Thank you for any assistance, advice or guidance you can offer!

First, switch the second parameter in the flow to a File parameter instead of a text parameter. Second, I've seen an issue lately with Power Apps adding a set of quotes around the Base64 JSON. So you need to strip that off when you send it to the flow See Substitute() below. But here is my working demo of the upload.

1) in onChange of an AddMediabutton control

Set(myimage, AddMediaButton1.Media);Set(myjson, JSON(myimage,JSONFormat.IncludeBinaryData));

2) In a button to do the actual upload

UploadFileFlow.Run(

"test",{file: {contentBytes: Substitute(myjson2,"""",""), name: "test.jpg"}}

);

3) in the UploadFileFlow
