Remove powered by Fluent Forms

I want to remove “Powered By Fluent Forms” from the pdf generated using your plugins.

I have used this code:

apply_filters ( 'fluentform_email_template_footer_credit', $poweredBy, $form, $notification );

PDF sample: Powered By Fluent Forms: https://ibcorner.com/wp-admin/admin-ajax.php?action=fluentform_pdf_download_public&submission_id=Tnk0MnlYZWZOeW1WUm5sQll3NVVGTmtnSEZraCtNVXNBdGp1K0ZrdFdoeTJleitaY3dmTTUySFFxM2lXb3NXU3pTRmdSWkxvMjJmNWtWdndnSUxaSEE9PQ==&id=OE5RL3ljdzlETjQ5Mlo4K3lnbG5vV0ZGTjNTckJuTkpRN3pYWDgvNy95cHNnVzQ5cUxBYWY4cmpHaHByNGhFTEl3TnY3T2FBSG5xTHM5VVNUeEVDNVE9PQ==
