How is Europe trying to stay relevant in the Ukraine-Russia diplomatic negotiations?

Europe is currently engaged in significant discussions in Brussels and Paris about maintaining relevance in a diplomatic landscape where the US appears to be negotiating unilaterally or bilaterally with Russia regarding Ukraine. European leaders are experiencing a period of 'soul searching' as they feel potentially sidelined in these important negotiations. This concern has sparked conversations about Europe's role and how it can assert its position in these diplomatic efforts despite the US taking a leading position in talks with Russia.
