Question about posting on LinkedIn

So I recently received an offer for this summer, and I wanted to post it on LinkedIn. However, the company gave me an approved blurb to post. I, however, wanted to post something else that's simpler, and also so I can include my team name and role name. The company-approved blurb doesn't include any of that. They did give me banners to use too, which I liked and definitely will use. Is it that serious if I don't use their approved message to post and will that be a bad look on me?
