Using rime input method, how create personal dictionary?

Question

I am using "rime input methods", ibus-rime on ubuntu 20.10.

I want to create a personal dict which could relate "zhuzizhuju" to "逐字逐句”.

I tried first to add dict option to "~/.config/ibus/rime/default.custom.yaml" as:

patch:
  schema_list:
    - schema: luna_pinyin_simp
      dict:
        - {type: phrases, filename: 'custom.dict.yaml'}

then in the newly "custom.dict.yaml":

---
-  zhuzizhuju: 逐字逐句

then redeploy, but did not work.
