Flight Details, Bank Statements, Family Details

Below are the checklist which mentioned in the UKVI Checklist pdf file after submission of Health Insurance and Visa payment.

Would I must have to submitted tour/ flight details either I have to plan to visit in Aug/Sep 2021?

Further, are Bank statements necessary to get the Global Talent Visa?

I already filled my spouse and kids details in stage 2 application, so what type of more information I need to attached like Family Tree of my own family or Parents and Siblings ?

Thank you.

I don’t understand why these questions even popup in GT stage 2. These are the visitor visa questions.
