Small bright lights appear in the sky, move around, and disappear

Yesterday afternoon, for the first in my life, I saw lights in the sky that I could not explain.
They were small but bright lights that would appear out of nowhere, move around, sometimes slowly but sometimes very fast, and then they would disappear. I have seen lots if different planes, drones, birds, insects, spider webs, misc debris, and other things in the sky. These lights had characteristics unlike anything I've ever seen before in person. In the attached video they kind of look like insects flying around, but in person it was clear that they were not insects. They appeared to be very high up in the sky. The lights were small but piercing, similar to stars. They would sometimes flicker or blink, often before disappearing. They have very similar appearance and behavior to some UFO videos I have seen online. I also took videos. At first my phone wouldn’t let me take videos. When I first opened my camera app on my iPhone it did not give me the option to take a video. But when I left and came back later it did let me. First time in my life that happened, too. I edited the most interesting parts of the videos I took together into the video attached below.
Usually there were just 1-3 of them in the sky at one time. I did see as many as 8-10 in the sky at one point, but I did not get that on camera. If you watch the video closely you will notice lots of them appearing and disappearing out of nowhere. They are very hard to capture on camera, especially because from my perspective they were flying around near the sun which was blinding both for me and for my camera. I used public data to confirm that the lights in the sky were not any known aircraft. I stood outside and watched these things for about 2 hours. I couldn’t believe what I was seeing. At one point I walked over to a landscaping crew and told them I was seeing things in the sky that I could not explain. At first they kind of laughed me, then one of them said “wait I see something” and then later said “you might be on to something” which I was happy to hear.
Later that night I went back outside but did not see anything. I checked again today and still have not seen anything like it.
