[BUG] How to handle GuildId when null? (ex. Starting Application from Direct Message)

[ETdoFresh]

Describe the bug
When starting the app from a direct message, the GuildId is null, which is totally fine. However, the only way for me to access the GuildId is via Dissonity.Api.GuildId. This returns long and not long? ... which causes exception when I try to determine if I'm in a DM.

Web Exception Console Log:
InvalidOperationException: Nullable object must have a value.

Reproduction
Try to access Dissonity.Api.GuildId when running app from a DM.

Expected behavior
Returns a nullable value or at the very least a predefined value (0 or -1 if no guild id exists).

Platform
WebGL (built from Windows)
Unity 2022.3.8f1

Good catch! GuildId should be a long?. I must have written that part back when activities only worked in voice channels and forgot to update it, which means that I should also test if other properties should be nullable. This will be changed in the next release.
