[Feature request] Inline math expression autocomplete suggestion

In Apple Notes (iOS and macOS), when typing a math expression followed by = it suggests the result. To accept the suggestion you can press the space bar, the tab key or command + -> . I would like to see this feature in Mattermost messages.

It also works in Apple Messages but it is more hidden on macOS as the suggestion does not appear inline; pressing two times the spacebar is one way to get the result.
