Employment Info hide fields based on assignment category

Summary:

Our client wish to hide a DFF based on the value in the 'assignment category' field when the employee is looking at their own record in the Employment Info page via ESS.

This DFF is allowed to be visible if the assignment category does not contain '(fixed term funding)' and they are viewing their own info, however we're having trouble getting this to work.

Can this be achieved?

Content (please ensure you mask any confidential information):

Below is the custom default we had before this new requirement. This means that the Fixed term end date DFF is visible for any employees regardless of their assignment category value
