View other library then general on Teams SharePoint site using iPhone
I got a solution from other source, however I was incorrect in my question, it was was viewing the folders within the general folder, nevertheless I believe the given solution would work regardless.
Below is the solution from Keyboarddredger at r/sharepoint
Within the Teams Mobile App, navigate to the Team and open the ‘general’ channel - add an ‘app’ (SharePoint is the App name). Then select if the SharePoint location is within the existing Team, or enter the URL directly.
If within the Team, use the tabs to navigate to Document Library and select from the list.
This applies for all users in the Team/Channel. I don’t think you have to use General channel but it is one everybody has access to by default.
Iconically, once you’ve added one document library via SharePoint app in teams the drop-down selector to switch to other DocLib’s appears.
