To change the word “Reset” you have to use ftp clinet, go to wp-content/plugins/pojo-accessibility/includes/pojo-a11y-frontend.php
Next open pojo-a11y-frontend.php file and go to line number 181 and you will see line like this
<span class=”pojo-a11y-toolbar-text”><?php esc_html_e( ‘Reset’, ‘pojo-accessibility’ ); ?></span>
Just change ‘Reset’ for what you want ??
Cheers
