Connecting Dashboards

Hello Everyone,

I am building a SaaS Platform “Vibe Coding in Advance”. Is the slogan. Not the name. But I need to know how to handle the different dashboards. Meaning the CEO Dashboard (the company dashboard)then the end users dashboard. The business that uses the company. The the end users customers. Similar to Shopify. I have coded the CEO business dashboard and coded the end users dashboard. I am thinking I need an overarching shell that covers all dashboards needed and somewhere somehow I need profile ids that sort, choose the right type of dashboard needed and using what I have already coded it pulls from that and creates the needed dashboard (say for the customer of the end user that purchased books?)I think I know how to make this work but what is the first step I need to do? I am using Java Script, VSC, powershell, python, vite. .jsx. once I am ready to launch I will use Vercel and Supabase.
