Historical City Hall, Münster, North Rhine-Westphalia, GermanyConstruction of the current town hall began in 1375 in the Gothic style and was largely completed by 1390. From then on, it served as the seat of the municipal administration and as a symbol of local self-government. At the beginning of the 17th century, the town wine house was built as an annex.In 1648, the town hall gained special historical significance when the Peace of Westphalia was negotiated and finally concluded in the building’s Peace Hall. This peace ended the Thirty Years’ War and is considered a milestone in European history. Over the centuries, the town hall has been renovated and expanded several times. In the 19th century, restorations were carried out that preserved the Gothic character of the building. During the Second World War, the town hall was severely damaged, but reconstruction began as early as the 1950s, largely restoring its historic appearance.

So, this is a flag of the LoN (to make it recognisable in this big event) and not the flag of the LoN. In addition, the League ceased its effective activities a few months after the beginning of the Fair because of the World War, the decision to create this flag is therefore not the product of a consultation between States but a simple illustration for communication purposes.

Switzerland joined the Council of Europe, a body dedicated to the promotion of good governance and human rights in Europe. Source — Wikipedia, "Timeline of Swiss history" (20th century):

The Flag of Europe is the flag and emblem of the European Union (EU) and Council of Europe (CoE). It consists of a circle of 12 golden (yellow) stars on a blue background. It was created in 1955 by the CoE and adopted by the EU, then the European Communities, in the 1980s. The CoE and EU are distinct in membership and nature. The CoE is an international organisation with 46 members, dealing with human rights and rule of law, while the EU is a quasi-federal union of 27 states, focused on economic integration and political cooperation. Today, the flag is mostly associated with the latter. It was the intention of the CoE that the flag should come to represent Europe as a whole, and since its adoption the membership of the CoE covers nearly the entire Europe by the number of states involved, although only a little over half of the European continent by territory. This is why the EU adopted the same flag. The flag has been used to represent Europe in sporting events and as a pro-democracy banner outside the European Union.
