Dataweave code in mule custom policy configuration

Question

I am working on creating custom policy in mule.

In configuration XML of the policy I am seeing various mule: transformers, set variable, loggers etc. while adding in before tag (<before/>) but dataweave.

I want to include dataweave code snippet in the configuration file (custom_policy.xml).

Can I have a chance to do that?

As per the example here you can use dataweave transform message component in your custom policy:

    <before>  

    .......
    .......
    <dw:transform-message doc:name="Transform Message" metadata:id="82cc8c48-d8bd-48aa-bf1d-ac1e7bc74f59">
        <dw:input-payload doc:sample="sample_data/json.json"/>
        <dw:input-variable variableName="jwtHeader"/>
        <dw:set-payload><![CDATA[%dw 1.0
    %output application/java
    ---
    "-----BEGIN CERTIFICATE-----\n" ++ payload.keys[?($.kid == flowVars.jwtHeader.x5t)].x5c[0][0] ++ "\n-----END CERTIFICATE-----"]]></dw:set-payload>
    </dw:transform-message>
