Manager wants me to be more extroverted

My skip level manager gave me the advice to be a lot more extroverted and this is further stressing me out. I do go out on team lunches and eat lunch with team mates but it looks like it's not enough. I'm bogged down by work as well.

He told me to focus on building connections, I feel like it won't add much value plus I am kind of doing this except not delibaretely. I'm a pretty introverted person who moves around like batman minding my own work and he doesn't like this plus I don't have time for small talk since my attention span is also low.

But he doesn't like all this and told me it's best i change how can I do this impossible task though, small talk is not natural to me plus I speak to only people I'm familiar with in general or if i really need something, I'm very introverted lost in his own thoughts
