Description

Following #334, this issue would create the base interface for data downloads. The work for this issue would entail:

• Creating most interface elements of this part of the Figma designs including:

  • Removing all legacy code that was added as a part of Menu item and interface for data download #334
  • The back button
  • The Download data header
  • The Update data section with all UI elements

• This issue does not need the Select data to download part of the UI

• Note: Blocked by Add data download UI button to installation tab (and add quick tutorial button) #565 where the button to navigate to this interface is made
