Question about allowable amounts of violence on canvas

I’m currently in the final stages of making my first episode and will be posting it to canvas soon “hopefully” it’s historical and revolves around people fighting I’m planning on having similar levels of blood and gore to chainsaw man or similar shonen manga but the advice I have seen for canvas is to try and keep the violence to around an R rating but I don’t think that would fit with the story what I’m asking is how acceptable is violence in webtoons cus if it isn’t I won’t be able to post there.
