Great Britain start the tournament with a lunchtime game against Spain on 28 July and are also in the same group as Australia, South Africa, United States and Tokyo runners-up Argentina.
French, from Ipswich, said: “Both pools are extremely tough, you’ve got the top four teams in the world competing and so every single match is a really hard game.”
But the team have already proved their ability to produce a result under pressure, having come through the FIH qualifiers bronze-medal match in January to secure their place at the Games.
“The Olympic qualifier back in January was crazy, it was probably the most pressure I’ve felt in an England or Great Britain shirt,” the Surbiton forward added.
“It came down to a one-off match against Ireland. They’re an extremely tough opponent and we knew it would be a very tight game.
“It was a 50-50 shootout of who got an Olympic spot and fortunately we were on the right side of the result. There was a huge sense of relief.”
