dAPP to token gate content for my NFT holders

hey there I have a new project. I have a chrome extension that I only want the holders of my nft to have access to. Anyone will be able to download the extension, but there is an on/off toggle in the extension menu. I want it that in order for a user to turn it on they have to connect their wallet to the extension and then have my nft in there waller before it can be fully turned on.
