What is the meaning of "Nabi Al-Malhamah" (Prophet of the Epic Battle) among the titles of the Messenger, may Allah bless him and grant him peace?

Lexicographers have mentioned two interpretations for "Nabi al-Malhama" (Prophet of thelma): The first is that he is the Prophet of fighting, supported by his (peace be upon him) saying: "I have been sent before the Hour with the sword until Allah the Almighty is worshipped alone without any partner." The second interpretation is that he is the Prophet of righteousness and bringing people together, supported by the fact that "lahm al-amr" (لحم الأمر) means its consolidation and reform. And indeed, Allah reformed the condition of the Ummah through him, unified its ranks, and reconciled their hearts.
