No one knows what what salesforce is except you, and you haven't provided a reference.
No one knows it's a web service.
No one knows what web browser you're using, which is very important in such cases.
People generally won't help you if you don't sufficiently explain the workflow you're trying to create.
People on this form are very helpful if you make it easy for them to help you.
Recording with Keyboard Maestro is generally worthless in creating a working, finished workflow – you have to know what you're doing and edit the junk out of the recorded macro – then you often have to add more focused actions for various steps.
Recording can be very helpful in learning to use KM and/or to get started creating a macro.
Clicking and scrolling in applications is very subjective and dependent upon a stable initial state, so this sort of action is generally unreliable.
Without having a salesforce account and being able to directly test, it will be difficult to help you.
There are various workarounds using a web browser's find function, Keyboard Maestro's Set Find Pasteboard action, and Found Image conditions, and a few other techniques.
You have to realize too that Keyboard Maestro works with the macOS User-Interface and that generally does NOT include UI that's built in a web page.
So – you've picked a somewhat complicated job to start out with.
If you can post images or movies (on YouTube) that show your workflow, it will be easier to help you.
Taking a quick look at the salesforce UI on Google Images I think you might be able to accomplish quite a bit using the click at Found Image condition, but it's hard to say without more complete knowledge of what your'e doing.
