Common advice is to build connection with other ND people. How?

Little grumble here, but a lot of people say I should try to find more neurodiverse people so socialise with, but how do I do this? It's nice chatting in online communities but it's not the same as real life connections. A social group of likeminded people would be amazing, but there's nothing where I live, it's all aimed at children or adults with learning disabilities. I would love to meet other late diagnosed, highly masking adults who can help each other to unmask. Something simple like a coffee or summer meet ups in parks, but nothing. There's such a gap in the 'market' or whatever you'd call it. Shame really, because a common question for many people who are trying to unmask seems to be, where can I meet likeminded people?
