IW Dropbox docs submission

I have scheduled the IW dropbox slot and below are list of docs they mentioned in the appointment confirmation to submit, actually i will be working in In-house project. so will it be any issues as can’t submit the end client letter.

Just have the employer include in the employment verification letter that you are a full time employee working on in-house project and there is no end client involved.

thank you so much Kalpesh_Dalwadi
