I hadn’t gone exploring through the settings till now. You can add a share button for your instance by going to Settings > Sharing > Add sharing method. After that you just paste in your instance URL (ex. https://lemmy.ca/ for me). The steps are the same for both Lemmy and Mastodon

Makes it much easier to share content here :)
