Ensuring Permanent Access for Lindy to Google Accounts

I have built a flow to create meeting agendas for my clients. The trigger is a calendar event starting (offset my -2880 minutes), and then the rest of my actions create meeting agendas. I am having trouble maintaining constant triggers due to Lindy periodically losing access to my calendar (which is hooked up via Notion but I don't think this is relevant). How do I allow for Lindy to have permanent access to my google accounts?
