A more thorough explanation:

An Advocate General is a legal officer who is appointed to advise the government on legal matters and represent it in court. In Scotland, this officer is appointed under the Scotland Act of 1998.

For example, if the British government needs legal advice on a matter related to Scotland, they may consult with the Advocate General. Additionally, if the government needs representation in court for a case related to Scotland, the Advocate General may be the one to represent them.

The role of the Advocate General is important because they provide legal expertise and guidance to the government, helping them make informed decisions and navigate complex legal issues. They also ensure that the government is properly represented in court, which is essential for upholding the rule of law.
