解决 TypeScript 中 el-popover updatePopper 方法不存在的错误？

Question

<el-popover ref="popperRef" placement="right-end" :width="400" trigger="hover"
@before-enter="getTicketAttachments(row.id)" :popper-options="{ boundariesElement: 'viewport', removeOnDestroy: true }"></el-popover>
<script lang="ts">setup(props: any) {

    const popperRef = ref();

const getTicketAttachments = (id: number) => {

        let req: any = { ticketId: id };
        cmTicketAttachment
            .Query(req)
            .then((rs) => {
                //downloadCallback(rs);
                state.ticketAttachments = rs.data;
            })
            .catch((rs) => { })
            .finally(() => {
                state.tableData.loading = false;
                nextTick(() => {
                    popperRef.value.updatePopper();
                });
            });
    };

return {

        getTicketAttachments,
        popperRef,
    };
},

运行updatePopper提示错误：Uncaught (in promise) TypeError: popperRef.value.updatePopper is not a function,原因是什么？？
