Is user_id length limited to 36 characters on Firebase JS SDK?

Because the data governance requirements for my project, I need to hash the user-id value with sha256 (sha256 value: 64 characters) and store in the user-id field in firebase/GA4/bigquery.

In Firebase analytic native APP sdk(iOS/Android), I already confirm the hashed user-id stored in firebase/GA4/bigquery correctly (64 characters). But in Firebase analytic JS SDK, I found the user-id in debug view is truncated only to first 36 characters, and the user-id in bigquery is also only 36 characters.

The official document doesn't describe whether or not there is this limitation. So, I want to make sure it.

According to this documentation there is no maximum length for the user ID.

The web client may have truncated the user ID 36 characters, which is being reconsidered at the moment.
