Instagram collaborators data

Hi Zernio team, I wonder if we can get the collaborator data outside of the one we created in Zernio! My team wanted to use Zernio as the tool, but before we move, we need to make sure that we can get the collaborator username from the historical posts before we migrate to Zernio. The https://docs.zernio.com/platforms/instagram#platform-fields only shows that the collaborator data will be shown once we upload it into Zernio. My request is for the historical data (manual upload directly from the platform)
