Based off of #20077 the copy can be aligned in both places.

I suggest:

ML flyout

There's no APM index pattern available. To create a job, please import the APM index pattern via the Setup Instructions <link to setup instructions>

Kuery bar:

There's no APM index pattern available. To use the Query bar, please import the APM index pattern via the Setup Instructions <link to setup instructions>

@sqren Although we might changing the copy so it reads "The use the Query bar, please import the Kibana Saved Objects via the Setup Instructions" if that's the copy the add data team is going with. Pending a final decision on their side before updating this.
