Granting Admin or Manager does not allow deleting or modifying process
Under team member there is no option to modify to manager. I can only view and invite however I cannot change the role

I think you are changing the role under the 'People' menu. For providing 'Delete' or Modify' rights for the card/ board, you should change the role of team member to 'Manager' within that project, under the 'Team Member' menu option. Please try it and let us know if you face any issues.
I granted access to a user to be admin and also try manager but still user could not delete cards nor change the process(lanes)
