Narrative: Upon arrival at the aircraft for preflight; Captain A and I found an ICAO Ramp Inspection underway. During our preflight; we spoke with ZZZZ Maintenance and with the Inspection Team that said there were a few very minor maintenance issues that were already taken care of prior to our arrival at the aircraft - a burned out light and [a] loose missing screw on the interior wall in the aft belly bulk cargo compartment and a few other items of little consequence. The inspectors then went through all of our pilot documents and safety equipment in the cockpit. This was followed by inspecting our flight documents such as the flight plan release; weight and balance; the Maintenance Discrepancy Book; our weather and NOTAMs; etc... He said we were 'good to go' and wished us a pleasant flight.We had already received all the necessary paperwork and clearances so we blocked out and eventually departed about 10-15 minutes late due to the inspection. When we arrived in ZZZZ1; Captain A's trip was over so he went to the hotel. I was to fly the same jet back to ZZZZ a couple hours later so I remained in the ZZZZ1 Operations building waiting for the next flight. I took the Inspection Report given to me by the ICAO Inspection Team and gave it to the EMEA Chief Pilot; who was in a meeting.A short while later my new Captain; Captain B; and I were preparing to leave the building to begin our aircraft preflight. We started chatting with [the Chief Pilot] who was out of his meeting. He asked me if Maintenance in ZZZZ 'wrote up' the repairs in the jet's maintenance logbook that were a result of the ICAO inspection. I admitted I hadn't noticed if those particular things had been written up but everything in the book was all current and signed off. Since Captain B and I were scheduled in the same jet for my return leg to ZZZZ; I double-checked to make sure the minor repairs made in ZZZZ due to the inspection; were documented. That is when we discovered [that] the very minor repairs had not been written up. Captain B and I contacted Captain A who told us to err on the side of caution and to not take the same plane flying until a definitive word had been reached on the airworthiness of Aircraft X. Captain B and I moved to another jet. ZZZZ1 Ramp did a fantastic job of transloading all the cargo; and we departed nearly an hour late for an uneventful flight back to ZZZZ. I believe it was a miscommunication and perhaps a misunderstanding on my part. I believed that tightening a screw and replacing a light bulb were part of a normal ground maintenance daily inspection routine that didn't require documentation. I must have misunderstood what the Inspector said when I heard the very minor issues were previously resolved and we were 'good to go.' [I suggest to have] better attention to detail on my part.
