We would like to determine if our application will comply with your SDA's

[#1]

We have read all terms of use and the developer terms SDA, but still it is a bit confusing, in your Spotify Developer Policy under term III.6.Do not synchronize any sound recordings with any visual media, including any advertising, film, television program, slideshow, video, or similar content.
Our application will be similar to Tiktok or Instagram where we will allow the user to overlay this uploaded video with Spoitify audio, the Video will be muted and the audio will play and this content that will be shared by this user to the public, there will no manipulation in the audio or mix ore mixed, and we will show the audio information in addition to Spotify logo while displaying the VIdeo.
