Customize Zoom UI using IOS Sdk

Hi, we are using zoom app for our meetings, and we came to level that we need to customize the UI with some additional features. Currently we managed to add the desired feature to open a pop up with external polling system....but the problem there are some missing features in zoom sdk version such as chatting and raise hand..but as i know from zoom support these APIs are available in sdk and we need to redo the ui things and use these API's endpoints. we need a freelancer with ios coding experience to customize zoom sdk and make these features available in the sdk as the one exist in zoom client app. if u are interested and ready to do this ... please bid and share your thoughts.... all general bids will be trashed and remarks as irrelevant
