How to give read, write permission for webform?

Hi all,

how to give create, read and write permission for custom web form?

Custom Doctype Permission are not refelected in web form. Is there any other way to give permission?

I had given read permission for role ex - ‘Test’ and then login with that role and access the web form i just need to read the web form not to write…but it allows me to write. Any suggestion guys.
