Need a help for display webform in created custom form

Hi,

I am created o custom module, I want to show a web form into this module. I am enabled the webform from content type setting, but still it is not showing the added fields in through webform. Can some one please help me.

I tried from my end:-
1) I have created one different content type and add this webform content type into previous content type with type entity reference. But this is visible only to backend user not for front end.
2) I have created one content form and published it and this form is used as block to show on form. but this is also not working for me.
3) I tried by enabling webform, that created fields are dispaly on form( webform and reports on top )

Above 3 options I tried, but it is not working for me.

Can you please help me solve these?
