How to remind my manager of a wedding gift he promised?

I have a friendly as well as professional relationship with my boss and my manager. My manager came to my wedding, while my boss did not because he was older and we are living in covid times.


Before the wedding my boss called to congratulate me and told me that he would send a gift through my manager who is attending.
My manager did not give me a gift at the wedding. But he called me afterwards to let me know that he will give me the wedding gift at a lunch meeting. We were pretty busy that day and did not get to talk in person. In the end, he was rushing to leave for another meeting. So I did not get the gift and he said nothing afterwards about that.
I want to remind him that I did not receive the gift but I don’t know how. It’s a gift so I am okay if I do not get it; and I am certainly not going to cause unhappy feelings at work for this.
But I feel I should point out because it has happened before that my manager would tell me that he is going to send an email or task to me and then forget to do so, while thinking that he has done it because he mistook the memory of the conversation for the actual sending/telling me.
I tried to mention to my manager about the wedding in passing and that did not prompt him to remember the wedding gift. Now that we are working from home, I cannot just knock on his door and talk in person about it. As I am doing thank you notes, I feel (fear) that both my boss and my manager thought they have given the gift.
How should I go about asking? Honestly I just want to avoid the situation where both my boss and my manager think they had given it to me.
