Open them up a little with a dremel or similar and heat the epoxy and work piece slightly so it flows better. Putting epoxy in the pinhole and then agitating it with a toothpick or paper clip after application will also help remove any bubbles that may still be present.

Your pin holes are air bubbles, don’t mix the epoxy too aggressively. As brad said, a little heat will help the epoxy flow better, just not too hot.

After the initial application, play a heat gun over the surface. It will heat and expand any bubbles and it will thin the material a bit. The combination of the two should make the bubbles rise and pop on the surface before the epoxy crosslinks.
Use a special self levelling formulation made for bar tops.

Fixing the pinholes after the fact is a lot of unnecessary work.

I think the toothpick idea sounds like the best idea for getting the epoxy into the holes.

I use a finishing resin for this. Zpoxy is a thin epoxy and will penetrate a deep crack very well. It is a 30 minute epoxy and does not bubble.
