Change table buttons text

Hello,

we have a table with all download using this shortcode

[wpdm_all_packages login=1 thumb=1 items_per_page="20" jstable=1 order_by="field_name" order="ASC/DESC" cols="title,file_count,download_count|categories|update_date|download_link" colheads="Title|Categories|Update Date|Download::155px"]

And we would like to change text and color for button for unauthorized users like this, but we see that the option doesn’t exist. Ex. Replace ACCESS DENIED with other locale.

Thanks
