Unable to view Word Templates in Dynamics 365 online

I have created system word templates for quote entity. Me being an admin can see them and run them for the records. I want users from another BU with particular security roles to view and run them but am unable to do so. I have modified the security role for the users for the particular BU and given them the necessary access. But still they are unable to view them under word templates. Also, when I try to give access via the enable security roles option in the word templates section, I only find roles for my BU and not the BU I want hence unable to give them access this way. What can be done? Thanks in advance.
