Not translable feedback “Send” submit button

The feedback “Send” submit button in the modal is not translatable. I cannot change the value of this input with PO file. The 54rd line <input type=”submit” name=”submit” value=”<?php echo esc_attr( ‘Send’, ‘wedocs’ ); ?>”> in a script “content-modal.php” looks like a bug. I suggest replacing this line with <input type=”submit” name=”submit” value=”<?php echo esc_attr( _e(‘Send’, ‘wedocs’) ); ?>”> Could you change the plugin and update new version?
