Python regex extract string between two braces, including new lines

Question

I have something like this

name {
    abc -> def{x};
    abc -> def{x};
    abc -> def{x};
    abc -> def;
    abc -> def;
    abc -> def;
}

I want to extract everything between the first and last braces {} so that the result looks like this

abc -> def{x};
abc -> def{x};
abc -> def{x};
abc -> def;
abc -> def;
abc -> def;

This is a different question because I am looking for everything between FIRST and LAST brackets.
