How can M.B.A help me in my career?

Hi All, I am a Java developer with >5 YOE, currently working in a low code tool. I see a bunch of my colleagues and friends are pursuing M.B.A which made me feel lagging. Could you please tell me

1. if this degree is relevant to me in my current position / generally for a dev. I mean, if I stay as a dev for the next 5 years, will an additional degree in my resume do any good?
2. Seeing BAs in different companies / clients that I worked for, I liked what they do and I might be inclined to take that role in the far future. My understanding is that BAs are still in touch with tech tools or most of them I've seen are, and hence I like this. Are there other similar roles?
3. Will an M.B.A be a deciding factor in roles like engineering manager, engineering director, head of business systems etc?
