Hi Experts,

I need to create a button called Edit record, it will open the current record in edit view and the user can change details and save. can anyone help me, I have written below however it's not working for me.
 

Template:

<template>
    <template if:true={showRecScreen}>
        <lightning-record-edit-form
    object-api-name={objectApiName}
    record-id={recordId}>
        <lightning-input-field
            field-name={nameField}>
        </lightning-input-field>
        <div class="slds-var-m-top_medium">
            <lightning-button
                variant="brand"
                type="submit"
                label="Save">
            </lightning-button>
        </div>
</lightning-record-edit-form> 
    </template>
    <lightning-button name="Update" label="Updateedit" onclick={handleUpdate}></lightning-button>
</template>

JS:

import { LightningElement,api } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';

import NAME_FIELD from '@salesforce/schema/Account.Name';

export default class Editrecordeditformpage extends LightningElement {
    @api objectApiName = 'Account';
	showRecScreen = false;

    nameField = NAME_FIELD;

 
	
	handleUpdate(){
	this.showRecScreen = true;  
	}

    handleSuccess(event) {
        const evt = new ShowToastEvent({
            title: "Account created",
            message: "Record ID: " + event.detail.id,
            variant: "success"
        });
        this.dispatchEvent(evt);
    }

}
