Safari keeps opening a website

When I'm using Safari, a specific website (for me, its a Notion page that I frequenlty visited) randomly opens in a new tab. It’s always this specific website (Notion Page). This happened like every hour or so. This notion page is not in my favorites or bookmarks. It's like someone clicked the link and safari open the website but I didn't touch my keyboard or trackpad at all. For example, if I’m watching Netflix in full screen, Safari exits full screen and opens this website out of nowhere. Anyone knows how to fix this? Thankyou
