Hi, very helpful video. Thank you. I just have some questions. I tested the user field and it works well. However, how can I make this field modifiable i.e. if a secretary is filling the form for her boss then she can remove her default name and add her manager's name. The other question, can we use the same formula to pull user's manager in the approver field? and the same, how to make that modifiable if we want to select another manager. Thanks for your help :)

Hi, I had a question maybe you can solve it. If I have an excel file as the data source and I create an app. When the user adds his id he must be able to see only his data(specific fields, not all the fields say if I have 5 fields name, surname, id, course, class, and school. when the user inputs his id he would see only his name and surname ) . How can I do this using powerapps? It would be great if you teach us this.
