slot prop cannot work in jsx in vue3

[jackchoumine]

<el-tag key={item.teacherName} size="mini" slot="reference">
       {item.teacherName}
 </el-tag>

slot="reference" worl well in vue2，but cannot in vue3. I have to write in h function:

 {
          reference: () => {
            return (
              <el-tag key={item.teacherName} size="mini">
                {item.teacherName}
              </el-tag>
            )
          },
  }

Does vue3 not support slot in jsx any more?

I hope use slot in jsx,it is close template.
