Expansive interconnected lights moving from East to West then heading straight up and out of site

I have never made any of this kind of report before, but I saw the most shocking, usual sight in my backyard back in May 2022 and just found your reporting website. I sent out an email with the details to what I thought was another reporting site the night I witnessed the event, but this appears more official and may be of value to you. The images that I saw that night have stuck with me and I didn’t even need to review my previously sent email as it was so startling, but have copied what I previously wrote below.
I was out in our yard in the Westsyde area of Kamloops, BC. 9:36 pm Tuesday May 10, 2022 when I noticed a group of revolving lights of varying colors (yellow, red, blue, green) in a triangular formation in the Eastern sky. The formation was highly visible spreading out for about a 1/2 mile low in the Eastern sky. The lights then started heading North West coming closer to where I was standing then started heading North as a large triangular group spreading out across the sky then started climbing higher and higher up into the atmosphere until they rapidly disappeared from sight. There was perhaps 8 or 9 lights of these varying colors all spread out in a formation.
This went on for about 5 minutes. I ran to the house multiple times to try to get my husband to come and see, but he didn’t know where I was calling from and by the time he came outside they were gone.
I have no idea what this was, but it sure wasn’t a plane or formation drones especially given the speed that it went up into up the sky and disappeared.
