is the part painted?
If so, take it to bare metal where it touches the frame and use a course grit.
Some surface texture will help the bond.
And yes getting the metal as close to the frame as possible is better.
Were you able to space the rivet gun so as to get into the corner?
Clean both frame and metal with a little IPA >90% or better on a cloth. (not the beer).
leave both to DRY, then leave them to DRY some more.
This removes the grease from fingers and any remaining dust.
After leaving them to dry long enough that you just can't stand it any longer, go a little longer.
Plan on adding rivets at the time the gluing takes place.
This clamps the part and stops any possibility of fracturing the bond by adding a rivet later.
Here's hoping all goes well

LASTLY - Have you popped a rivet ahead of time?
Depending how strong the rivets are, you don't want to pull the rivet all the way through the carbon.
If it feels like that might happen, consider not pulling to POP, but pulling partially and cutting off the rivet very gently after the glue sets.
