It looks like edema. Also, some plants release sweet sap to attract insects like ants that ‘guard’ the plant from insects destructive to the plants. The sugary sap can crystallize.

Doesn’t look edematous to me, but Sunny is definitely right about the second part. The plant has what are called extrafloral nectaries. Totally benign but it’s a good idea to wipe the leaves down with a damp cloth ~weekly to remove the sap/crystals. If left on there you can get discoloration of the leaves, which often looks like yellow or orange spots.

Nectaries can also be a sign that the soil is a little more water-retentive than the plant would like, but you can disregard that if it’s in a well-draining/chunky mix
