Translating the main editor widget which displays the titles of content types

Hi, I have been translating content type widgets into Korean, but I have yet to find a way to translate the main editor widget page which displays the titles of content types and details button as shown in the attached file. I am using H5P in Moodle 3.9.2 version. I have the impression that currently it is not possible to translate the main editor widget page from reading some forum topics related. However, if my understanding is wrong and there is any way to achieve this task of translating the page, please let me know. Thank you. Have a great one.
