Is Bitcoin a native token?

Excuse me, but I have a question regarding the classification of Bitcoin. I've heard people discussing whether Bitcoin is a native token or not. Could you please clarify for me what exactly is meant by a native token, and whether Bitcoin falls into that category? It seems to me that the term 'native token' might be used in different contexts, so I'm seeking a clear and concise explanation to help me understand Bitcoin's position within the cryptocurrency landscape. Thank you in advance for your assistance.
