Connection time in Lille Europe between Eurostar and THalys

I have a booking from London St Pancras to Lille Europe on Eurostar and then another on Thalys to Amsterdam. The connection time is only 29 minutes and I am concerned that it won't be enough time for me to make the connection as I have some mobility issues (cannot walk long distances in a hurry) particularly when pulling my luggage.

Also, I noticed that there are enhanced security measures in place now in Lille Europe requiring passengers to report at least 20 minutes prior to departure.

Will I have sufficient time or should I try to exchange my Thalys booking to a later train?

Thanks for your help
