Zoho Writer saves to Zoho Docs by default, can't change to WorkDrive.

Zoho Writer saves to Zoho Docs by default, can't change to WorkDrive.

I'm on a trial of Zoho One.  Zoho Writer's default save location is Zoho Docs despite Zoho Docs not being activated in Zoho One (WorkDrive is).  I have to change the save location to WorkDrive via the dropdown selector but if I forget, it saves to Docs and I'm left thinking my document disappeared when looking for it in WorkDrive.

I see no way to change the default to WorkDrive, how do I do that?

I see no way to remove Zoho Docs, which is not activated, from the dropdown selector in Writer, how do I do that?
