Hi! That's just a small flag in the GRC YAML definition of your block, not actually 
anything functional that you need to write yourself. just add this line to your GRC block 
definition:

flags: [throttle]

(or, if there's already a "flags" property, add ", throttle" to the list)
This ideally goes right after id: and label:, just like in 
https://github.com/gnuradio/gnuradio/blob/main/gr-soapy/grc/soapy_sink.block.yml#L5

Best regards,
Marcus
