Already understood how to do.
I made a workaround, created the route, and this is the controller:
async createMany(ctx){//É preciso fazer harcode, fazer db.query.createMany
let body = ctx.request.body;
const response = await strapi.db.query('plugin::rc.channel').createMany({data: body.data})
return response;
},
With the strapi.db.query strapi actually uses the lifecycles hooks. So you can put the code in the lifecycle.
