CORS Problem when including Yasgui in an spring-boot app.

Hi there,
i am currently trying to replace my simple html form with Yasgui. in the HTML form i have a hidden field which is set dynamically.
the input filed name is '_csrf' the value e.g.  'efh_4uOZ...'.

I should be able to transfer this parameter somehow with Yasgui. i have not found a configuration parameter in this direction. How can I transfer the CSRF info with Yasgui?
