I have a vf page which needs to be visible in both classic and lightning experience. I added lightningStyleSheets="true" to enable lightning kind of styling in lightning experience for the page.
However, when the page is viewed in lightning experience, the sidebar and header get disappeared. I checked for it, so it's because the lightning experience overrides the sidebar and showheader to false by default. But how can we make this available in the lightning experience? I tried with "setup = true" . But this enables setup bar in classic only, and when tried in lightning experience, the classic setup gets visible. Has anyone worked on this?
