How Do I Output Multiselect Attribute Values In Magento 2.3.x?

In a Magento 2.3.3 store I am trying to ouput the values of a multiselect custom attribute on a category page, but not having any luck.
I have set the attribute to be used in product listing and tried to output it on catalog/product/listing.phtml template page in my custom theme.
I am using the using the following code:
<?php /* @escapeNotVerified */ echo $_product->getResource()->getAttribute('custom_attribute')->getFrontend()->getValue($_product); ?>
This is working for dropdown attributes but not multi select attributes.
Kind of stuck on this…

    You can use the below code to get MultiSelect Attribute value

    create block in “catalog_product_view.xml”

    <referenceBlock name="product.info.main">
    <block class="MagentoCatalogBlockProductView" name="attribue.name" template="Magento_Catalog::product/view/attribute_name.phtml" after="-"  /> 
</referenceBlock>

    create “phtml” file under “Magento_Catalog::product/view/attribute_name.phtml”

    <?php $product = $block->getProduct(); ?> 
<div>
  <?php 
    $data = explode(',',$product->getData('attribute_code'));
    foreach($data as $value):            
  ?>
  <?php 
    $attr = $product->getResource()->getAttribute('attribute_code');
    if ($attr->usesSource()): 
  ?>
        <?php 
            $option_value = $attr->getSource()->getOptionText($value);
        ?>
        <p><?php echo $option_value; ?></p>
    <?php endif;?>
 <?php endforeach;?>
</div>

    Here is an example of a code that returns "Multiselect Attribute Values". The attribute belongs to product entity. As it isn’t a good idea to get ProductResource model from ProductModel and taking into account that probably you need to get it inside some template, just create a ViewModel and use this example there.

    use MagentoCatalogModelResourceModelProduct as ProductResource;
...
public function __construct(
    ...
    ProductResource           $productResource
)
{
    ...
    $this->productResource = $productResource;
}

public function prepareProductAttributeOptions($product, $attributeCode)
{
    $result = [];
    $data = $product->getData($attributeCode);
    $optionsIds = [];
    if ($data) {
        $optionsIds = explode(',', $data);
    }

    foreach ($optionsIds as $optionId) {
        $attr = $this->productResource->getAttribute($attributeCode);
        if ($attr->usesSource()) {
            $option_value = $attr->getSource()->getOptionText($optionId);
            $result[] = $option_value;
        }
    }

    return implode(',', $result);

}
