Inherit Issue Tracker List Comment Column in Custom List

Hello All,

• I am  creating a ticketing tool using "issue tracker list" and designing the UI using Power Apps , And later I came to knew there is a limitation in Power Apps as it can not pull "Issue tracker list".
• So I had created the Custom list to meet my requirements.
• There is Comment column in "issue tracker list" which gets blank automatically when we edit the list item, So that users can  reply or comment for an item.

So can any one please guide me in getting Comment column in "issue tracker list" to Custom List

Thanks & Regards,
Siddiq.
