Capture groups recursively with regex between braces

How to write a regex, that capture every group of these structures?

Tried this, but this just captures everything (.*{.*}$)

Want to have a group for each so that I can extract each one individually

NewRequest {
    string id = 1;
    string name = 2;
}

NewResponse {
    int64 id = 1;
    string name = 2;
}

Complete structure:

NewRequest {
    string id = 1;
    string name = 2;
}

 NewResponse {
    int64 id = 1;
    string name = 2;
}
 NewResponse {
    int64 id = 1;
    string name = 2;
}
 NewResponse {
    int64 id = 1;
    string name = 2;
}
 NewResponse {
    int64 id = 1;
    string name = 2;
}
