Hello @alinemorelli,
I think that adding the nonce parameter to your library will be a great improvement 😁
Can you have a look to my PR ?

[tonytamps]

There are now 2 PRs for nonce support @alinemorelli and a lot of people are very keen on it.
Is there anything we can do to help get either of them merged?

We need to merge this PR.

How can I help to make this happen?

[seancswanson]

Add me to the list of people who would love to see this merged. Anything further we need to do @alinemorelli ?

Seems like someone forked and made https://github.com/irsooti/react-gtm-module-nonce, but that's out of date as well, with the react dependency causing problems.

Maybe @pastuxso could take a look?
Adding a nonce has become the default security recommendation for GTM tags.
