Calendar Issues

I have an iMac. I used to be able to schedule a meeting. When I did, immediately, my calendar on my Apple computer would open and, with a simple click, I had all the invitation information. I could then go to my email and copy and paste the invitation and off it went. Terrific. Now, with changes that I don't understand, I have difficulty finding the invitation. If I find it, it has the Zoom link that I can copy, but the invitation doesn't give the time or date of the meeting. I would like the "old" way back of scheduling something and being able to get the full invitation on my Apple calendar. Can you help me?
