If you delete the trust wallet app and reinstall the app as long as your assets still appears  I think they are suppose to show you the transaction history, although I haven't done that before but I'm pretty sure that all your transaction history will still appear, have you tried doing that and they refused showing you your transaction history? Or you just want to ask to know if it's possible? You should try and read threads of those people who has done that before I think they can have answer to your question.
