Making a shortcut for checking null component in unity

Evetime I create a new component in unity, I something like

if (!TryGetComponent(out _rb2D)) {
            Debug.LogError($"There is no rigidbody component in the {transform.name}");
        }

if (!TryGetComponent(out _rb2D)) {
            Debug.LogError($"There is no rigidbody component in the {transform.name}");
        }

So I created a shortcut

            </Literal>
          </Declarations>
        </Snippet>
    </CodeSnippet>
</CodeSnippets>

but when I use it, I get this

    if (!TryGetComponent(out )) {
            Debug.LogError(ComponentName

    if (!TryGetComponent(out )) {
            Debug.LogError(ComponentName

this is not what I want, where is my

 Debug.LogError($"There is no $ComponentName$ component in your {transform.name}");

 Debug.LogError($"There is no $ComponentName$ component in your {transform.name}");

message? and why there is nothing here

  if (!TryGetComponent(out )) {

  if (!TryGetComponent(out )) {

for me to edit? and hi it dosent close the if

because string interpolation uses $ aswell as the placeholder in the snippet you would have to escape it i guess never done it but you could try \
