Have you heard of Toggl? It's a time tracker that integrates with your browser and let you click click click on Google Agenda meetings, JIRA tasks, GitHub PRs and hopefully most of the tools you use, to track how much time you spent on it. I've used it since 2017 and it was a game changer: helped me reduce multitasking, produce factual invoices when billing hourly, identify what ate all the time in my day...
I'm sure there are also other alternatives out there but Toggl is the only one I have experience with.
