Set up your field, let’s say a text component, and a user-specific boolean column, let’s say “VisibleText”.
Set the text component to be visible when VisibleText is not True, then in the screen, add a switch/checkbox that lets the user switch/tick and point that value to the “VisibleText” column.
When the user has switched/ticked that component, the text will not be visible anymore.
