Boris Johnson is in deep doo doo - he was humiliated.

42. The Queen is somewhat similar to

a Governor General (GG) in Canada (and some other parliamentary systems).

The Queen or GG must approve the dissolving of Parliament and calling of an election (as Johnson recently requested), can dissolve parliament on his/her own and, approve all legislation passed by parliament (called Royal Ascent) i.e. the Queen is the "head of state" and GGs represent the Queen in here capacity in other countries once affiliated with Great Britain.

The Queen or a GG rarely go against the wishes of the government but have the power to do so if extreme circumstances warrant.

Such a thing might be very useful in the US if the US had a parliamentary system and tRump was Prime Minister (leader of the party with a majority in the House of Commons). IIRC, in systems of government that have both a President and PM, the PM is the government leader and the President has powers similar to the Queen or a GG.
