No you can only create profile delete profile set proxy or other operations like these which can be operated from API, you can't access your webview with ix in BAS, I know why you want to use ix or other Anty detect browser, because BAS is easily tracked in some projects, I am also facing the same problem. And I am trying to find a solution for it.
If you find any solution please share with me
It’s called a module in BAS. In your project check the ui tools on top. Select the functions you want to export and that’s it. Later you can enable or disable for any other scripts
