usability – Full screen cookie banner on mobile, is it a bad or good approach?

I am developing a cookie banner for a company. The designer presented all the mockups, but I am not convinced whether it should be full-screen on mobile. The advantage is that the user might be seeing all the banner text at the same time, but you are forcing him to see that instead of the website he intended to visit. On the other hand, a half-width cookie banner is having the lorem ipsum text having to be scrolled down, which is also not optimal
