I work in MS Powerapps where i have a gallery. I want to filter this Gallery with a TExt input field. I have setup a code for this, but it leads to a delegation problem. Do you have any idea how i can fix it? please provide a code and use semikolon instead of comma:  (IsBlank(Textsearch.Text) || Titel & 'Activity Type' & 'Training Topic' & Audience & Level= Textsearch.Text)
