How do I create a product along with it's pricebooks at a time?

Question

I'm using lightning-record-edit-form to create a new Product field. I need to create it's pricebook values along with it. How do I achieve this? I tried nesting record-edit-form but it isn't working.

Here's the code:

<lightning-record-edit-form object-api-name="Product2" onsubmit ={handleSubmit} onsuccess={handleSuccess}>
                            <lightning-messages></lightning-messages>
                            <div class="slds-m-around_medium">            
                                <lightning-input-field field-name='Name'></lightning-input-field>
                                <lightning-input-field field-name='ProductCode'></lightning-input-field>
                                <lightning-input-field field-name='Description'></lightning-input-field>
                                <lightning-input-field field-name='Family'></lightning-input-field>
                                <lightning-record-edit-form object-api-name="PricebookEntry">
                                    <lightning-messages></lightning-messages>
                                    <div class="slds-m-around_medium">
                                        <lightning-input-field field-name='Pricebook2Id'></lightning-input-field>
                                        <lightning-input-field field-name='UnitPrice'></lightning-input-field>
                                    </div>
                                </lightning-record-edit-form>
                                <footer class="slds-modal__footer">
                                    <lightning-button label="Cancel" variant="neutral" onclick={closeModal}></lightning-button>
                                    <lightning-button label="Save" variant="brand" type="submit" name="save" ></lightning-button>
                                </footer>
                            </div>
                        </lightning-record-edit-form>
