Amend footer text shown to valid patrons

I want to amend the footer text shown to valid patrons. I have locked content that is available at any qualifying tier.

At the moment the text inside patreon-valid-patron-message div shows " This content is available exclusively to members of {patreon} at $0.01 or more." (in Chrome) and in Safari the $0.01 is rounded to $0.

I want to remove the “at $0.01 or more”. I’ve tried using valid_patron_final_footer. I can overwrite the existing text; however I’d like to keep the initial “This content is available exclusively to members of {patreon}” (with dynamic Patreon name and URL) and remove the Patreon tier information.

This is what I have so far:

// Amend footer text shown to valid patrons
add_filter( 'ptrn/valid_patron_final_footer', 'update_patron_footer_text');
function update_patron_footer_text($content) {
  $content = "this is custom text"; // change text here
  return $content;
}

That should work. You can use the functions in the plugin to check for the conditionals used for showing different text if you wish.
